Hi, I’m completely new to fish tanks and today I acclimated a Chocolate starfish for about an hour. Adding some of the tank water to the water that was in his little baggie and he’s now just chilling in one spot and I don’t see any of his little fingers. I’m worried about him. Is he okay? He’s been in the same spot for about 10 minutes now and he hasn’t fixated himself to the rock. There’s also the little brown string on top of him. Is he okay?
