Actually I did get one from LFS. They had 4-5 of them so I took some small rocks with aptasia on them to see which one would eat aptasia the best. Put him in what was my NPS tank 36" long 17" tall 30gal. He did eat all the small ones but not interested in the larger ones. Just last week I took that tank out, & put in a 30 breeder. The 30 breeder will be a frag tank with a 250w MH. So the Copper Band is now in the 180gal. He seems to be doing fine, but there is only larger aptasia in the 180. Luckily they are really nice fish so if he doesn't eat any of the larger aptasia it's OK. I'll post some pix of new frag tank when I get the light from a friend that is breaking down his tank.
