Which would be better for a reef tank having primarily easy, soft corals (mushrooms, polyps)? Also, I realize my tank is relatively small (56 gal) for either...are they both about the same size in eventual growth and need for swimming space?
Actually, the H. acuminatus, the Pennant Coralfish, is a polyp consumer and is NOT REEF SAFE, but the closely related H. diphreutes , the False Moorish Idol (Schooling Bannerfish) is a schooling planktonic feeder and is reef safe. Also there is the Red Sea Bannerfish H. intermedius, also reef-safe, a drifting plankton feeder. As always, these are still butterflyfishes, ans as always, may not have read the books...babyblue1977 said:here are 2 links to the reef safe
