Hello, this is the typical firefish goby going MIA question. So, I haven't seen him in about a week, he usually comes out to eat. I've been trying to peak in my rockwork, but don't see a body, he does have a den somewhere down there. I'm not going to break up my rock work, but how long would you go without seeing him before you count it as a loss? 3 weeks maybe? I do have a decent CUC, so if he is dead, they'll get to it for sure. Only other fish in the tank are a pair of clowns and a Watchman
