The size and type of the tank
The smallest social unit when it comes to otos is obviously a couple. This fish feels bad on its own, without a companion of the same species. In such a case, without any other stocking, an aquarium that does not exceed 30 liters is sufficient. However, otos are rarely kept in this way due to the fact that they are not particularly ornamental. For this reason, with a larger group, for example 8 individuals, the aquarium should have a capacity of up to 100 liters. The more fish of other species, the larger the tank should be.
As mentioned, otos can do well in multi-species aquariums. They need adequate space, but also a large number of plants and hiding places, especially located near the bottom and up to the half of the water level. Make sure that there is a cover on the aquarium, and at the same time the water surface is in motion and free from floating vegetation. Remember that otos also breathe atmospheric air, so they swim to the water surface and take in the air accumulated above it.

This will prevent poisoning with nitrogen compounds resulting from the decomposition of ammonia.
