Care notes
Black-and-white striped, very hardy. Becomes a tyrant with age. Often regretted later in reef tanks. Best in fish-only or with large robust fish.
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.
