Addis butterfly
Keep the Addis away from Yellow tangs — the shape is too similar and the butterflyfish tend to get harassed. However, if you can afford to, get a group of five and keep them in a fish only set up with lots of live rock (they’ll browse over the live rock). Housed with similar sized fish or smaller, Addis butterflyfish will become some of the most confident and outgoing fish in your tank.
