Wasn’t sure what group to post this in. But I put a nem in my tank a few days ago. He was attached to a rock when I got him. He stayed in place for a few days then this morning I woke up and he had moved to a little cave between two of my rocks. Then maybe a hour later I noticed he moved deeper in to where I can’t see him anymore. Should I be worried or will he be able to get himself back out since he got himself in there?
