El catfish is also well known as the 'pacifier' or 'pool cleaner', more than anything because this specimen helps to keep the aquarium clean. It bears that name because of the whiskers on its head that are very similar to those of felines. Some even clean the walls of the fish tank, which is an excellent fish that keeps the aquarium in perfect condition. They are also perfect to put them in any fish tank.
The only thing that must be taken into account when incorporating them is the size of the tank, since these fish they come to reach 30 cm in length, and this could be a real problem for the aquarium if it is of normal measurements. You only have to choose the catfish in its smallest species if your aquarium is small.
The main job catfish do is keep the fish tank clean. By feeding fish from the top of the aquarium, some of the food is forced to end up at the bottom of the aquarium. Without benthic fishLike deep-feeding catfish, uneaten food can foul the tank and reduce water quality to dangerous levels.
However, when choosing the fish, keep in mind that it is a very territorial species both with yours and with different ones, so if you notice that there are conflicts, it is necessary to separate them. Although it is believed that catfish feed on everything they find at the bottom and with the algae that they clean, it is not the case that they feed properly like the rest of the fish.
Nor should we forget that they are a tropical species and therefore they need a heater to keep the water at its correct temperature.
