AQUARIUM CARE: These very small catfish are an excellent addition to the aquarium. They are fairly hardy and will do a good job keeping the tank clear of unwanted algae. If there is no algae, some vegetable matter is greatfully received: cucumber, lettuce, blanched spinach etc.

Otos make good community fish, obviously avoiding too large or predatory species. Clean water is important, maintain water quality.

BREEDING: Substrate spawner, though rarely achieved in the aquarium

Fishkeeping Facts and Tips

Low light plants Java moss, Java fern, and several of the Anubias species all do fine in low-light conditions. That is not to say that they do not thrive with stronger lighting, but in an aquarium with a lot of floating plants, or one with timid fish that prefer a dimmer tank, these plants are very useful indeed. All are epiphytes; that is to say they need not be planted, and can be attached to stones, bogwood or just left free floating
