Hello everyone ,it's been awhile that i have asked for suggestions on RC, but I have a small thought. This weekend I bought 2 small banded gobies and introduced them to my tank. They seemed very happy and immideately started borrowing in the substrate. I have about 4 inches of aragolive sand. I have not seen them since. My question is, "is this normal?" The hole that they built has been covered somewhat by a lowmower blenny who like to hang around the area where they built the hole. I have not seen them since. Do you think that maybe the cave gave way and they became trapped and died? or could they have moved to a new home? When is the best time to check and see if they swim around? Any Ideas?? Thanks in advance.all
