Care notes
Stunning powder blue body with yellow dorsal and black face. Notoriously prone to ich and HLLE. Quarantine essential. Needs strong flow and lots of swimming room.
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.
