Im looking to add what would be the feature or marquee fish to a 56 gal
tank that has a yellow tang, kole tang and a flame angel (all about the same size, 2-3 inches), along with simple corals such as mushrooms and polyps. Lots of live rock, live sand, UV
filter, all good equipment.
I was thinking maybe a butterfly, if there are any that would be okay with this type of reef. Maybe a threadfin, or possibly a banner fish. I like angels also, but I gather most are not reef friendly.
Looking for a fish that wouldn't grow beyond, say, 6 inches.
Thanks for feedback and ideas!
