My awesome little tail spot blenny disappeared today. He is in my 10 gallon tank so there is not many places for him to hide. I have a tightfitting acrylic top I made myself. When I went to feed this morning I put the pumps in feed mode and left the top up. He always comes out when the pumps turn off. My guess is that he jumped out after I was done feeding this morning and one of my dogs got him. If that is not the case what is the possibility of him getting stuck inside of a small hole in my rock work?
