funny. When I was reading the post, once I saw that it was a loach, I was just waiting to read, "oops, I found him!" They are amazing at hiding. I don't even look for them anymore which is huge for me. They come out a few times a day to play and eat. I don't even bother putting pellets or algae tabs in the tank unless they are out. Will never find em in my tank. They hide good.
