Tiny labyrinth fish requiring extreme blackwater conditions (pH 3.5–6). Conservation-critical species — many wild populations endangered. Not for beginners. Species-specific tank recommended. Males display with iridescent blue-red markings.

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.
