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

Should I have water movement in my tank? Fish from faster flowing rivers love swimming against a current - fish from vegetation choked marshes do not. With todays box filters it is quite easy to get some good water flow for strong swimmers like Rainbowfish, whilst a spray bar attachment can completely remove this for gentler swimmers like Gouramis
