I have a 90g that gets direct sunlight. I had a GBTA that had a perfect spot:inlove:. He dicided to go for a walk one night:bunny: and i couldn't find him:banghead:. When I did, 3 days later, it was under a rock all the way in the back. Needless to say, he was then a White BTA :supermad:. I put him back in the same spot. The next morning, he was on the other side of tank under another rock. I stepped out, came back and he was gone.....:Yikes: presumed :dead1: I filed a missing anemone report but, that didn't go over well. So, I purchased a RBTA and now my b/w clown loves him:hug: and it hasn't moved from the same spot that the GBTA was.... still looking for him...:google:
