(Other members of the genus Otocinclus)
ADULT SIZE: 5 cm
WATER CONDITIONS: Not critical
TEMPERATURE RANGE: 20-26 C
FOOD: Feed Otocinclus affinis a predominantly vegetarian diet
DISTRIBUTION: This species comes from Brazil
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

Sorry no records.
Should I get rid of snails? Snails in the aquarium can be very useful. Many fishkeepers tend to overfeed a little, and this extra food sinks to the bottom and decays, polluting the aquarium water. Snails will happily come and eat up the left overs though - if you have an outbreak of snails you are most likely overfeeding your fish! If you really do want to remove snails, fish like the clown loach, and several puffers will eat them - but do make sure they are compatible with the other fish in your tank
