Hey guys, yesterday I went to my LFS and he did a water test and everything was good so I bought some fish. I got a spotted puffer, a pink anthias, a watchmen, and a firefish. It seems whenever I get close to the tank they all hide behind the live rock, and when I feed them they won't come out. I know they're all healthy and eating cus the owner of my LFS fed them in front of me. I spent a good bit of money on these fish, and would hate for them to die from hunger. Anything I can do? I'm feeding them shrimp pellets.
