I just got a green clown goby today. He didn't look too good in the bag (mailed from Live Aquaria) but seems to be mostly recovering now. The SG in that bag was only 1.021. Anyway, his tummy looks awfully sunken. Is that normal for clown gobies since they wedge in corals? He likes the fake pink Acropora coral in the tank. He doesn't seem to be the kind of fish to actively feed. What should I offer him? What do your clown gobies eat? I normally feed with "nano food" pellets and a frozen blend of half a dozen frozen saltwater foods and Cyclopeeze. Since my tanks are small, I mixed up a batch of food and froze it in mini ice cubes. Each cube is very small but has a lot of variety without the waste. So far, I haven't seen signs of eating. Aside from sitting in the fake Acropora, he will sort of dart to the various corners of the tank and act like he wants out desperately. That's pretty normal for new fish but I'm worried. Thanks.
