Midget sucker mouth catfish
Otocinclus affinis
Part of a large family of Loricariidae, the Otocinclus is one of the smallest. It is usually tan with a black peppered body. Found in rapidly moving rivers, the Otocinclus swims and moves using its sucker-type mouth.
This catfish should be housed in at least a 30 litre aquarium, with high filtration along with high aeration. A planted tank with rocks and driftwood will provide plenty of hiding spaces to prevent the fish from becoming stressed. This unique fish is an ideal candidate for the planted aquarium, as it will consume algae that grows on the leaves of plants.
A planted tank with high vegetation and some algae will sustain the Otocinclus. However, if algae are not present, supplement with a vegetable-based flake or wafer food.
