Like monks with a hangover, red eye monk tetras display bright red eyes and are very friendly and sturdy. Red eye monks tend to school in the lower levels of the tank and need to be kept in groups, or they can get a bit aggressive.

Care Guide
Tank setup: Give them plants along the back and sides, open swimming space in front and a dark substrate, which brings out their color. Keep a lid on the tank, since tetras can jump.
Feeding: Feed a quality flake or small pellet once or twice a day, only as much as they eat in a couple of minutes. They also enjoy frozen foods like bloodworms and brine shrimp.
Tankmates: They get along with most peaceful community fish of similar size, such as other tetras, rasboras, danios, corydoras, dwarf cichlids, gouramis and livebearers.
Good to know: Tetras feel safer and show better color in a group. A larger school also spreads out any chasing.
