Tonight I took the blanket off the tank and turned all the lights off in the house...except my desk light. Waited about 1/2 hour till everything was calm in the tank. Dumped some bloodworms right over the ray. After about 5 mins he came out and started foraging. He seems to really like being under this very large root that I have. He ventured out almost to the middle of the tank, then seemed to get a bit uncomfortable and found his way back to the security of his root. All in all he was swimming and eating...acting normal... For about 1/2 hour, then buried himself again.
I am so damn happy right now....can't wait till he swims freely with the lights on.
