Hi again. Sorry the photo didn't get attached. You could definitely see that he really was stuck. The most recent time, he was stuck between a rock and the glass, and I couldn't move the rock. He tried to swim forward but made no headway at all, and we ended up pushing quite strongly on his "neck" with a rubber coated scraper handle until he finally dropped to a clear area below. After that, it took him a few minutes to regain his equilibrium.
I feel that if we could have less rock in the tank, and of lighter material, that at least we could move the rocks, if not him.
