Saltwater fish for tanks: Fish groupings

It is of utmost importance to understand which fish do not go together in saltwater tank and to keep this in mind when considering the future development of the aquarium.

There are basically three kinds of species: fish, which must be kept as single species inside a tank, the predatory fish and the friendly fish.

The ones which must be kept unmixed with other species are for example damsels, labridae, canthigaster. These are very aggressive natured fish and they would attack others in the tank and therefore they should not be mixed with other species.

The predatory fish should not be mixed with smaller fish as they would basically become their food. Some examples of these are the diodontidae, muraenidae, zanclidae.

The third, more friendly small fish group can live together with other similar fish with no problems. Pacanthurus haparus, anthias, clownfish are examples of these.

Saltwater fish for tanks: Tips

It is important to consider what the fish eat, because many saltwater fish die in aquariums due to the improper diet they receive. So an important indicator when choosing a saltwater fish for tanks is to make certain that the specific species are well suited for aquariums.

Damsels are very territorial and aggressive so if you are just starting out you may want to stay away from them. They attack fish many times their size. Especially if you plan to develop your tank it would be an issue to mix these with other such as clowfish or angels.

Green chromis do belong to the damsels family but they are not aggressive at all, so that could be a better option to go for. They are also quite pretty and change colours when you look at them from different angles. They seem to do better when there are uneven quantities of them in the tank.

Yellow brotulid is also a good choice but requires some maintenance. Otherwise blue-lined pipefish or pygmy seahorses are less demanding on maintenance.

Another option is to not put fish but go for something like mantis shrimp.
