I need help with my goby, for easter my grandmother picked me up a watchmen goby for my biocube yesterday. It went under the main peice of live rock, and have only seen him once since. The only time i saw him the emerald crab was attacking him and he was breathing heavily. I havent seen him since, and im kinda worried that the crab may have killed him, i removed the crab and he is in another tank. I don't know wether i should move all of my rock and look for him, or wait and see if he comes out.
