The sun catfish (lat. Horabagrus brachysoma), which is also known as eclipse catfish, can often be seen in tanks nowadays, though it’s not a fish for everyone. This article has information about how large the fish can grow and who it represents danger to.
Habitat in the wild
The fish is endemic in Kerala state, India, and it dwells in Kerala backwater areas, in Vembanad lake, the Periyar and Chalakudy Rivers. The fish prefer thickly planted areas with slow water flow. As a rule, these are low-land river areas and backwaters with a muddy or sandy bottom.
Horabagrus brachysoma preys on insects, mussels, and fish. Adult species of the fish can eat ground insects and even frogs. Having such a flexible diet is very convenient in the changeable life environment, where food availability depends on monsoon rains.
It is known that the fish becomes more gluttonous during its spawning period and the months that follow the monsoon season.

Difficulties in keeping
It is an undemanding fish. However, it won’t do for community tanks.
Firstly, this is a predator fish, which will prey on its tank mates.
Secondly, the fish becomes more active in the evening and at night, while it prefers hiding during the day.
This catfish has a large head and eyes, four pairs of barbs (on the upper and undertip, and in the corners of the mouth). Fish has a yellow-colored body with a large black spot near its pectoral fins.
It the internet, you may see the information that the sun catfish grows to be a small fish, about 13 cm long. Most aquarists think that this is a small-sized fish, but this isn’t true. In fact, the fish can grow up to 45 cm long in the wild, while in a tank, its size doesn’t exceed 30 cm (12 in).
Keeping in a tank
It is a nocturnal fish, so you should provide it with dim light and lots of shelters in the tank (snags, small stones, flowerpots, and various tubes, etc.).
The fish produces a lot of waste, and for successful keeping it in the tank, you should use an external filter.
Recommended tank water parameters are the following: temperature 23-25°C, pH 6.0-7.5, hardness 5-25°H.
It is a predator fish, so it prefers eating live fish. Nevertheless, it can also eat various food in a tank – live, frozen, artificial.
Compatibility and tank mates
This catfish quite often are sold as fish for community tanks, but actually, you mustn’t keep it in one tank with small-sized fish species. This catfish will eat everything that it can swallow; thus, its tank mates should be of the same size or even larger.
The best tank mates are large cichlids and other catfish species. Young species feel good in a company of their kind, and they even can create schools, while reproductive species of this catfish prefer solitude.
