I got a rainbow BTA and have had it for about a week. He seemed to be hiding from the light for too much of the time, which I eventually learned was because of light acclimation. So yesterday put in a a screen of 3 sheets of parchment paper between the tank and light and now he's reaching for the light again. But he doesn't look very brown to me. Has all the zooxanthellae died? Is there anything I can do? When do you think I should start removing some of the sheets of parchment paper?

On a related note, he doesn't seem healthy enough to sting the cleaner shrimp when she climbs across him; he just retracts his tentacles instead. Is this normal? Also, when will the cleaner shrimp leave the BTA alone? When I got the BTA, the shrimp changed her station to be on the rock over the BTA and still bothers the BTA from time to time. I haven't even fed the BTA yet, so I don't think she's going for food (except maybe plankton that the BTA catches from the water? Do cleaner shrimp eat that?).
