the butterfly picks at the rocks, and the only food i've been able to get it to eat is brine shrimp.
It is very cool watch, and hope it does well I've only had it about a week.
I noticed a "spot" just a day after adding it to my tank. It looks like a internal bump about the size of a dime, and dark incolor. I don't know what it is but as i sadi I hope it makes it.
