What are the differences (both physical looks and behaviorally/physiologically) between the heniochus butterfly and the moorish idol? I thought they were the same fish but apparently they are different. Thanks!
Big difference!Moorish has that beak and the streamer on the dorsal.A more beautiful fish but the most difficult.I can't believe mine is still alive after really not eating anything.They do require very large tanks and do well in schools.I only have one in my 90 and doing okay considering him not eating much.
