Care notes
Schooling fish; keep in groups of 5+. Will eat all plants in the tank. Good dithers for large cichlid tanks. Related to piranha but entirely herbivorous.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
