Emerald Catfish - in The Aquarium

In The Aquarium

The emerald catfish is a common species in freshwater aquaria. It is a peaceful, undemanding species and can be maintained under the same conditions as most Corydoras species. They are shy and easily frightened when kept as individuals, so it is best kept in small groups of at least three, with more being recommended. The tank should have only a soft, fine bottom to prevent damage to barbels and should be heavily planted. Feeding is not difficult and they accept almost anything, although live worms are especially appreciated. It does well in a community tank and does not tear up the plants.

Spawning has been achieved in captivity. Typically, the fish are separated into a breeding tank in the ratio of three males to two females, all well-conditioned on live foods. The couple will spawn while sitting on the bottom, not while swimming as many similar species do. In captivity, the female collects the eggs in her pelvic fin basket and pastes them individually to plants and other objects. Eggs will be deposited by the female throughout the tank, but especially on any floating surface plants. According to most reports, the parents do not immediately try to eat the eggs. The eggs hatch in about four days and the fry become free swimming two days later.
