New Bubble Tip Help

So I got this guy 2 days ago. He looked good and healthy. Drip acclimated him for an hour and put him in the tank on the piece of rock he was attached too. He detached right away and strolled back and forth and settled about 5 inches from where I original had him. He looked really good the first day but now he keeps shriveling up. His foot is still attached well and doesn't seem to be disintegrating. I had a carpet in the tank before and he did really well doubled in size in 6 months but he started to get an expensive appetitive. Anyways I'm like a new mother and I wanted to know if what the RBTA is doing is normal or should I worry. I have 2 clowns in there but they havent been interested yet. My peppermint shrimp messed with him a bit when he first was placed but they lost interest.
