Care notes
Beautiful red-green pattern resembles US flag. Excellent algae eater — great for planted tanks with pest hair algae. Can be nippy; best with robust tankmates. Hardy cold-tolerant species.
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.
