Bring on the FISH!
I have been watching a critter on the rock for a couple of weeks not and have not seen another one in the tank. I have not added anything that could have even remotely housed a hitchhiker like this in a couple of years. It looks like a clam and moves like a clam. It’s about ¾ inch long and blue in color. The shell is white and it appears to be long ways into the rock like we are looking at on side of it, not the top view, I thing.
