   My Experience (summary of my own keeping)

A couple of my favorite nicknames for these fish are "little monkeys" or "water monkeys." Otos cling to aquarium glass, rasping and scraping the surface, eating the algae growing there. They do best in numbers, although older specimens are fine on their own. The only negative about these fish is that they can be sensitive to water quality, but otherwise they are an aquarist's best friend, "swinging" from surface to surface in search of an algae treat.

Otos are very common because of their small size and useful utility within the aquarium. Algae is the staple of their diet, but do not rely on them to do all of the work themselves. Per any aquarium, frequent algae scraping is still a necessity. Otos do help, however, and are well worth it. In aquariums with an abundance of otos or a lack of algae, algae supplements are encouraged.

Side note: I would truly enjoy it if "water monkeys" became this fish's new common name.
