Lost Clown Goby

[Pier Pressure]

I bought a yellow clown goby about a week ago and it is always hanging out at the front in the corner of the tank, about halfway down. Funny thing is if I open the lid to feed he takes off into the rocks. I have seen his reflection in the back of the tank and he does seem to be darting out quick and then back into his little hidey hole at feeding time so I think he is eating. I can see them being very timid, though, and not showing themselves for a long time.
