NMreef...the butterflys do seem to be a bit finicky eater. these two are pigs, but I have noticed they seem to like the frozen mysis the best...but they do eat pellet formula 1, not 2 so much, and they also graze on the three different seaweeds I alternate with, brown,green and purple...so hopefully. If these don't make it , I guess I have to assume my tank is just too small for them. Wierdly enough the nicest fish in my tank, the naso tang, was bothering the racoon for awhile :notsure: But now they seem fine together.
