Hello everyone, Friday night I got two baby clowns from the LFS. Drip acclimated them both carefully. They are the only fish in the tank. At first they were just swimming in one corner of the tank and after a few hours they both went this little nook and haven't come out. They just lay in there. Also it seems like they're digging a deeper cave with the sand. This morning one of them were laying sideways, when I got up close to take a look they switched spots and the other one started laying on its side at the very inside of the little nook. It's been two days now and I don't think they have done a full lap around the tank. Should I be worried? Thanks for your time.
