Jester, I have had my copperband for over 3 years now. Mine doesn't know what an aiptasia is either. When I got mine it was a mixed up fish order by my LFS. This fish was about the size of a quarter. I started it out on the Piscene Energetics brand of mysis shrimp and there has been no turning back. This fish will flat chow them down. This is the flat pack I'm sure someone was mentioning. The cubes are about the size of brine shrimp and not worth anything compared to the PE brand.

HTH...
