Looking good...nice rock work. I'm glad you don't have to deal with dinos. On my first set up several years ago I had them and it was a challenge to get rid of them. I did but almost threw in the towel over that crap!! So far with my new set up all is dino-free!
Sorry to hear about your clown going awol. I recently put a yellow eye tang in the tank and it was doing well for 2 weeks. Then one morning I don't see it with the rest of the fish. Upon lifting some rock work I found it wedged between the sandbed and a rock. I literally had to pull it out from under the rock, it was really wedged!?? Strange things do happen in reef tanks!
Looks like you had fun at Fragtoberfest!! So did I brother!
