Compatibility aquarium fish OK- a very important question for beginners and experienced breeders. Each fish has an individual character, style of behavior, regardless of whether it is a herbivore or a predator. Some fish quickly eat plants and shrimp, while others attack the fish themselves. Of course, there were cases when practically incompatible species coexisted calmly in one tank.
Moderately aggressive fish
They are as forgiving as aquarium fish, and even among their normally freshwater relatives, you can find firmer fish. Incidentally, this of course means that they are extremely resistant to disease. This quality alone should automatically attract them to most potential owners right away. They rarely succumb to the common marine parasites that give them head now and later in captivity, and in over 20 years of keeping marine fish, this author has never lost a trigger fish for any marine fish disease.
Aquarium Fish Compatibility Chart
To systematize this issue, you should familiarize yourself with the habitat conditions of each hydrobiont, and then decide who to add it to. Assess the degree of aggressiveness of each species, the water parameters that are acceptable for them, in which layers of the reservoir they usually swim. To keep your aquarium full of life, a table is provided that lists the compatibility of freshwater fish species.
However, it should be a good enough indication of the family's inherent well-being as a whole. Having said that, there are Trigger species that, while still hardy by most standards, won't do as well with this treatment. Let's start by choosing the right tank. Some triggers always end up alone or go back to the fish shop, no matter how much they tolerate tankers when they are young, so the aspiring trigger should keep that in mind when choosing which species to keep.

Often, beginners make a common mistake by populating completely incompatible species in an aquarium. As a result, the fish begin to eat each other or arrange fights. To prevent this from happening, we recommend using the aquarium fish compatibility table, which will help you choose the right inhabitants. home aquarium.
Aquarium fish compatibility: typical mistakes of beginner aquarists
Others will live their lives in communal settings with few problems if enough space is provided, some storage order rules are followed, and tank mates are chosen with some care. Some will even live in reefs. In any case, tall, narrow tanks should be avoided, as they are very active animals and need as much swimming space as can be provided.
A hex tank is a very poor choice for a trigger unless it is very large. Unculled trigger fish. As with many families, the wide range of adult sizes, growth rates, and temperaments makes it difficult to generalize about minimum tank sizes. Further complicating the issue is that although this species can reach 14 in the wild, this does not necessarily mean that this size is realistic in captivity, even if kept in the largest home aquaria.
Aquarium fish compatibility
To choose the right inhabitants for the aquarium, you need to know exactly which breeds can get along with each other. If you plan to keep crayfish, shrimp or other unusual inhabitants, their features must also be taken into account.
Below are descriptions of the main breeds and their coexistence with others. The author of the video will tell you how to choose them for your home aquarium.
Others are simply extremely slow breeders and are unlikely to achieve anything close to adult size even after 6 or 7 years in captivity. While fish of this genus are without a doubt one of the most easily kept and sociable of all trigger species, they are also very slow producers - annoyingly slow if the truth is known. If you need good example for adults, you have a true exercise in patience before you unless you acquire a person who is already in the 7 or 8 inch range.
For this reason, a young sample, say in the 2" range, can be purchased and conveniently housed separately in a 40 gallon tank for at least 12-18 months before large facilities are required. Long term, 70 gallons will usually do, because once they reach 5 or so, their growth slows even more. Among them are Niger Trigger, Queen Trigger, Clown Trigger and Blue Line Trigger. All four are relatively fast producers and require very large tanks as adults.
angelfish
Scalars are not very accommodating. The developed instinct of a predator leads to the fact that angelfish attack their small neighbors and eat them, and even get involved in fights with larger breeds (table 1).
Note: If angelfish fry are settled with others, and they grow up together, coexistence will be quite peaceful.
Table 1. Coexistence of angelfish with other inhabitants In addition, angelfish can become prey for larger predators. Therefore, it is better to grow this breed separately, or to add breeds that can easily dodge angelfish (for example, zebrafish).
Predatory aquarium fish
We are talking about 500 gallon plus for the queen and at least a 200 gallon tank for the other 3 species. This almost always changes at some point, so be careful! The queen is developing too fast to consider anything other than a very large reservoir because of this. Having said all that, a 70 to 80 gallon tank will provide enough space on a long-term basis for the vast majority of triggers likely to run into your local fish store if left alone.
Even with more sociable species, you will be very limited in terms of suitable companions, even if more space will not be provided. However, in this hobby, as in all things, nothing happens all the time, and triggers can and do get sick if not cared for properly once collected. When looking for the right animal, make sure it is sturdy, with no concave or sunken areas on the sides. One of the most common problems is malnutrition due to lack of proper nutrition, and fish that are not of the proper weight should be avoided.
Loaches
Loach fish feel quite well in closed reservoirs. Due to their special lifestyle, they get along well with other breeds. This is due to the fact that most loaches are active only at night, and during the day they burrow into the sand and rest (Figure 1).
Figure 1. Features of loach aquarium inhabitants It is difficult to accurately determine the coexistence of loach fish by photo and name. Much depends on the volume of the container and the nature of its inhabitants. Best of all, they get along with plecostomuses.
Basic principles for choosing aquarium fish
The prospective keeper should also be on the lookout for cloudy areas or spots on the eyes, fins, and body, as well as bad color. Very small specimens can sometimes be difficult, and some species are more prone to problems here than others. One of the worst in this respect is the "Clown Trigger" and very small inch-long specimens often only last a few weeks in captivity.
However, keep in mind that Trigger should be the smallest fish in the tank, and specimens in the 5" range and larger usually make excellent choices. Of course, the trigger must be large enough to prevent it from being consumed by larger fragments that may already be present in the system. As mentioned above, some triggerfish species are more suitable than others for long-term cohabitation with other fish species. While these species can be kept with other species when small, trying to keep them in a community setting when they start to overlap at some size usually ends in tears - this is a very powerful and potentially very destructive fish.
Guppy
Guppies are one of the most popular pets and are great for beginner aquarists. They are unpretentious, hardy, and a wide variety of colors allows you to create an aquarium of unique beauty.
Since guppies are small and peaceful, they do not get along well with large predators. They simply eat guppies, preventing them from breeding. Therefore, it is better to select peaceful breeds of small and medium size as neighbors (Table 2). These include zebrafish, cardinals, neons, small breeds of tetra and, in some cases, swordtails.
The recommendations provided here are intended to provide the keeper with a long-term farming solution. Luckily, there are species that usually do well when mixed with other harsh marine species in large blocks. More than one triggerfish of this genus can even be kept in the same tank, but they should be introduced at the same time to avoid serious territorial aggression.
Unlike some species, it will grow to full adult size in a reasonable amount of time if cared for properly. In fact, in all cases, your Trigger must be the latest and smallest fish added to the community. The reason for this is that even relatively peaceful species like Huma Huma are only peaceful in relative terms! They are still quite aggressive fish and can do significant damage when interbreeding. For this reason, they usually should not only be added last, but also be the smallest fish in the tank.
Table 2. Guppy cohabitation with other inhabitants Mollies
Representatives of this breed are very mobile, therefore, the aquarium for their maintenance should be spacious enough. In addition, they are thermophilic and react negatively to sharp fluctuations in temperature.
Simply adhering to these two rules will usually ensure that the Trigger does not establish itself as the dominant fish in the community and allows other residents to adapt to the Triggerfish's presence. For their part, triggers are usually immune to the stress of larger, intimidating tank mates, and they are reasonably well armored against anything short of attacking in depth! These species can be kept in reef setups and often even bother small shrimp if the shrimp are introduced before the trigger.
Unfortunately, this practice is usually the result of ignorance rather than knowledge that sooner or later other conditions of life must be made. Just remember that soon you will have to give something! Several anomalous cases where people can get away with it on a short time should not convince you to try - be careful! Having said all that, as long as the aquarist follows a few rules and uses some common sense, tank mates aren't hard to come by - there are plenty of options, in fact.
For the joint cultivation of mollies, medium-sized viviparous breeds (swordtails, platies), labyrinths (lyalius and gourami), as well as some types of angelfish and bettas are most suitable (table 3).
Table 3. Coexistence of mollies with other aquarium breeds However, you should be careful with the latter, as they tend to show some aggressiveness. In addition, soft water is preferred for angelfish and bettas, while hard water is more suitable for mollies.
These fish are beautiful, hardy and intelligent and contrary to common perception, they are not usually aggressive towards members of other families. However, they are more than assertive and tough enough to hold themselves in the presence of most balistoids. In fact, varying degrees of physical injury poses a risk to any slow moving or relatively sedentary fish species kept with certain triggers. An unfortunate incident and a reminder that the destructive potential of these fish should not be underestimated, and sailors should choose wisely.
Plecostomuses
Plecostomus is a special breed of aquarium catfish that requires a lot of space (Figure 2). The length of an adult individual can reach 60 cm, therefore, when breeding, decorative snags and other shelters for rest should be provided in advance.
Figure 2. Appearance and physiological features plecostomuses Representatives of the breed are nocturnal, eating algae and cleaning off pollution from the walls of the aquarium. Thanks to this feature, plecostomuses get along well with almost everyone. An exception can only be representatives of the same species, if they are planted in an aquarium with an already adult individual.
Corridors and cockerels
Triggers almost without exception should be the last fish added. In fact, the dream tank that this author aims to keep to the day is a 120 gallon voucher with one adult bloat trigger. Now the aquarist has to face the challenge of dealing with the extremely destructive abilities of these fish, and nothing is safe!
That means filters, power cords, power cords and heaters! For this reason, these items are best stored in the sump and out of the main tank. They are also skilled at tipping and moving rocks and other decorations. Speaking of things to leave out of the main tank, add your hands and arms to the list! As far as possible, you should avoid putting your hands into a tank with large triggerfish - they can draw blood, and larger specimens can remove fingers.
barbs
Barbs, regardless of breed, have a rather complex character: they often start fights with other inhabitants of the aquarium (Figure 3). Moreover, aggressive behavior concerns not only representatives of other species, but also relatives. For this reason, it is not recommended to keep more than six barbs in one aquarium at the same time.
The jaws of these fish are very efficient for what they are designed for, which eliminates all sorts of hardened objects found in their environment. Most species feed on hard invertebrates in the wild, so they spend their day browsing the reef for crabs, shrimp, snails, etc. in captivity they will accept a wide range of fresh and cooked fish food, leaving it up to the aquarist to offer a variety of foods, and that vitamin supplements be administered now and then to ensure proper nutrition.
Since barbs are very active, and love to bite others by the tails and fins, cockerels, veiltails and angelfish are absolutely not suitable for them as neighbors. It is also not recommended to keep them with peaceful guppies and goldfish. Predators are also unsuitable neighbors for barbs, since in this case they will already be attacked.
In addition to the many suitable foods that can be bought in frozen form at the very best fish stores, an aquarist can drop the seafood counter at their local grocer and find many things that will contain triggerfish from the hands of keepers in no time flat. Some of these items are fresh squid, octopus, scallops, fish, shrimp and crabs. These foods can be cut into bite-sized pieces and offered a trigger 2 or 3 times a day.
Even the few available species that are plankton in the wild readily accept and develop all the variants mentioned above, with the exception of large invertebrates. One thing is repeated here, and this is important for vitamin supplements. This predator is a consumer of items of the whole animal. When a Trigger consumes a crab in the wild, it not only ingests the meat, but all of the blood, organs, and other matter that makes up the animal, not just the meat. Feeding a combination of whole foods and vitamin supplements alleviates any problems that my rear part head goes down the road from behind malnutrition including but not limited to bad color.
Figure 3. Species diversity of barbs The best neighbors for barbs will be swordtails and bots, although several types of barbs can be kept in the same aquarium at the same time.
cichlids
Most cichlids have an aggressive nature, so they have a hard time getting along with other species. However, there are also peaceful species that feel great with other inhabitants of the aquarium (Figure 4).
Figure 7. Cichlids and their coexistence with other breeds Cichlids are absolutely incompatible with zebrafish, guppies, gourami, goldfish, bettas and catfish. In some cases, you can add bots and eels to them, but you need to constantly monitor the pets, and in case of disagreement, they should be settled in separate tanks.
Goldfish
All aquarium goldfish were artificially bred, although they were obtained from silver carp. For this reason, they get along well with koi, telescopes, and other peaceful medium-sized individuals (Figure 5).
Figure 5. Features of goldfish In addition, several types of goldfish can be kept in one aquarium at the same time. However, in this case, it should be borne in mind that they will begin to interbreed with each other and the purity of the breed will be lost. For this reason, if pedigree breeding is planned, each species should be kept in a separate tank.
Gourami
In general, gourami have a peaceful nature, and show aggressiveness only when attacked by predators. But there are species with which gourami will feel uncomfortable. These breeds include goldfish, koi, cichlids, bettas and parrots. Maintenance problems can arise when gourami are bred with discus, guppies or shrimps at the same time (Figure 6).
Figure 6. Coexistence of gourami with other aquarium species When choosing neighbors for gourami, preference should be given to zebrafish, angelfish, barbs, tetras, haracin species and catfish. Most of them are medium-sized and quite mobile, so they will not claim personal space for gourami. Catfish generally lead a nocturnal lifestyle, so during the day the gourami will feel absolutely free.
Danio
Danios, regardless of the species, get along well with almost all species, but the advantage should be given to medium-sized species, such as guppies, bots, labeos or scalars.
The only caveat applies to the veiled zebrafish, whose long tail may be of increased interest to individuals with a more aggressive nature. For example, cichlids, eels, and even goldfish may try to bite off a zebrafish's tail or fins, so this neighborhood should be avoided.
Discus
The main problem in the joint maintenance of discus and other breeds is that they need a sufficiently high water temperature, which other inhabitants of closed reservoirs simply cannot withstand (Table 4).
Note: However, experienced aquarists are still advised to keep discus separately from other species. Firstly, they are quite large and they need a lot of space. Secondly, they are slow, and more agile inhabitants will eat food faster.
Table 4. Scheme of coexistence of discus with other aquarium inhabitants In addition, discus belong to cichlids, so they can be aggressive towards smaller neighbors. To prevent this from happening, it is better for them to provide a separate aquarium, and bright colors and unusual shape discus will help make it a real decoration of the house.
corridors
Corydoras belong to the catfish, so they do not have an aggressive character and get along well with almost any species.
Sword Compatibility
Swordtails are very popular aquarium pets. This is due not only to their unpretentiousness in care and maintenance, but also to their peaceful nature. They get along well with all small peaceful breeds (table 5).
Table 5. Coexistence of swordtails with other species Among the best neighbors for the swordsmen are small neon, guppies, zebrafish and blackthorns. However, they will also feel good when living together with catfish, angelfish and small cichlids. However, it should be borne in mind that males can be more aggressive towards each other, so it is better to keep one male and several females in one aquarium.
Labeo
Outwardly, labio are very beautiful representatives water world, but with their content, certain difficulties may arise due to their pugnacious nature.
Fry usually behave peacefully, but as they grow older, they show more and more aggressiveness. If you still want to start a labeo, there should be only one individual in one aquarium. You should also avoid fish that are similar in color and shape, as the labeo will attack them. As neighbors, it is better to select small and fast individuals: barbs, congos and danios.
Pecilia
These fish can be called truly universal. They get along well with almost any species, do not require special conditions for keeping and feeding, therefore they are suitable for beginner aquarists.
Even in small aquariums, platies do not attack other inhabitants, and if the capacity is large, they find a secluded corner and do not violate the territorial habitat of other species.
Astronotus
Astronotus are one of the most aggressive aquarium fish. For this reason, they can be kept either in a separate tank or together with spiny fish (for example, Synodontis).
In addition to poor livability, the species also has one more feature: they eat almost all plants and move decorations. Therefore, it is better to place overall artificial plants. However, astronotus quickly get used to a person and do not show aggression towards him, and thanks to a developed mind, they can even learn to eat from their hands.
Botsii
The bots belong to the loach species. They are quite large and at the same time mobile. They spend most of their time at the bottom, so they can be kept in a community tank without any problems (Table 6).
Table 6. Bots compatibility However, it is better to choose medium and large fish without long fins as neighbors. Small inhabitants of a closed reservoir can simply become a victim of bots, and in individuals with long tails and fins, bots can simply cut them off.
Rainbows
Rainbows belong to peaceful species that feed on plant foods. Therefore, you can keep them with any other species. Predators are still best avoided, as even a large iris can become their victim.
Aquarium crayfish compatibility with fish
The issue of coexistence of aquarium crayfish with fish is twofold. Crayfish are exotic inhabitants of the home aquarium that do not require special care (Figure 7). It is important to choose the right fish for joint maintenance. Some species are absolutely not suitable for the neighborhood with crayfish, others get along with it quite peacefully.
Note: Some aquarists believe that crayfish are able to eat even large species a slave, and during the molting period, the crayfish itself, having lost its scales, can become easy prey for predators. This is partly true, but much depends on the nature of the cancer itself, the mobility and size of the fish.
Figure 7. Compatibility of aquarium crayfish with fish For joint maintenance, you should not select slow individuals or species living near the bottom. They will become prey to cancer very quickly. Bright and large species that attract cancer are also not recommended. It is best to keep crayfish in separate containers or add fast small fish to them, for example, guppies.
From the video you will learn how to properly keep crayfish in an aquarium.
Shrimp aquarium compatibility with fish
The physiological characteristics of aquarium shrimp determine their compatibility with other inhabitants of the water. In nature, shrimps hide from predators in the soil, algae and any other objects in the reservoir (Figure 8).
Figure 8. Species diversity of aquarium shrimp In order for shrimp to get along well with fish, you need to carefully select all aquatic inhabitants. Any large fish can eat a shrimp, as long as it is large enough to swallow. Very quickly, they will begin to perceive shrimp as their favorite food and destroy all individuals. For this reason, they cannot be kept together with gouras, swordtails, goldfish, angelfish, discus and bottom breeds.
Note: Immediately after purchase, shrimp should not be placed in a community aquarium. They will immediately begin to hide from the fish, which will certainly begin to hunt for them. In this case, the shrimp will quickly become the prey of other inhabitants or die from stress.
Shrimp are very interesting creatures, so it is better to keep them in a separate aquarium. But if this is not possible, then it is better to hook them up to guppies, neon or any other small species. However, a separate container will still have to be purchased for keeping newborn shrimp. They are so small that even peaceful neighbors can eat them.
To choose the right inhabitants for a home aquarium, many nuances should be taken into account. Firstly, each type of fish requires its own temperature, hardness and aeration of the water. Secondly, species differ physiologically and may not get along in the same tank. In addition, in a closed pond there should be an optimal amount of algae and decorations so that the fish feel comfortable.
Table 7. Aquarium fish compatibility The compatibility table (Table 7) will help you cope with the task of selecting fish and other inhabitants of the aquarium. With its help, you can properly populate the aquarium, choosing the right inhabitants.
