Care notes
Males brilliant deep red; females olive-silver. One of the most striking rainbowfish. Needs hard alkaline water. Males display intensely; recommend 1:2 M:F ratio. Lake Sentani endemic — wild populations threatened.
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.
