My Yuma keeps moving around the take. He will stay put for several days and then move. I don’t change flow or anything. I came home from work three days ago and he was cozied up to my rock flower anemone. I immediately moved them and the ricordea looks fine. My rock flower has looked bad ever since. This morning he has a brown spot on the top and he released from the rock. His mouth is still next to the brown spot.
