Care notes
Bold patterned fish with venomous dorsal spines—handle with caution. Excellent algae grazer. Generally reef-safe but may nip corals if underfed on algae. Hardy and adaptable.
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.
