Thanks for the warning, Fox. I've had him since I think October 21st (may be the 22nd, but somewhere around then). He's never gotten on the rocks at all to my knowledge. I've tried to see with a flashlight when the tank lights are on, and he spends all night on the powerhead. He seems to really like it. Anyway, I'll keep my eye out.
And on an unrelated subject, why are the shipments always late on the LFS that we both go to? Supposedly they always come in by 5 on Wednesday. Since I got my tank, they're always late, but they're always in late Wednesday night so when I go on Thursday morning the corals have had time to acclimate to the show tanks. Today, they're not going to be open until 4:30, which probably won't happen either. He's always an hour late on fish shipment day. It's so sad that my week revolves around the new shipment. Enough with my venting, this was supposed to be about nudibranchs.
