Since we are on the subject. I have another question about CBS. i just bought one from SWF. I put him in the tank yesterday. I have not seen him since. I don't have any aggresive fish that I know of. (2 Perc clowns, Green chromi, 6 line wrass, and a Pajama Cardinal). I do have ALOT of LR though. He may just be hidden where I can't see him. Is this common?
