Dwarf Suckermouth Catfish - Otocinclus sp.
This is a Restricted item and is not covered by our Arrive Alive 5-Day Guarantee.Please see our Guarantee Policy and Restricted Species List for more information.
There are two commonly imported species of Otocinclus catfish, Otocinclus vestitus and O. mariae. They are often mixed together in shipment. There are also several other more uncommon varieties.
These fish are characterized by a brown dorsal color, a horizontal black stripe running the length of the body, and an underslung, sucker-like mouth. They are very popular algae eating fish as they eat micro algae without damaging the leaves of aquarium plants. They are very small, only reaching a maximum of 2 inches.
Otocinclus should be kept in small groups, but be sure to keep no more than 2 per each 5 gallons, or they will run out of food. Some driftwood should also be provided as they will graze it for algae. Because of their small size care should be taken to avoid any predators that would make them a quick meal. They are peaceful and make one of the best housekeepers in a freshwater tank.

Cute little things
These are amazingly cute catfish and are good with all my other fish but they might die if you clean your tank wrong (in my case)

I had no idea how much I would come to love my school of 5. Not only are they absolutely adorable but they keep the tank really clean. I love that they stay small and press themselves against the glass so I can see their full tummy's. They work well with my Fancy Goldfish as they don't bother each other.
these fish are so cute and absolutely love the algae in my tank will be buying more soon
