Care notes
Variable coloration depending on population — some are spectacular orange-red-blue. Hardy Australian rainbowfish. Active schooler needing space to swim. Males spar harmlessly at dawn displaying colors.
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.
