My tank looks empty now
But I'm happy your clams are back home where they belong! That is one of the nicest derasa's I've ever seen. If you ever decide you're tired of it ....
Sorry to hear about the one piece receding but your other frags are looking well (better than mine ... I'm tempted to try moving them out of the coral-nippers tank, but I'm a little paranoid about putting SPS in my other tanks!)
Gorgeous mandarin. Seems to me they come in bursts .. you'll see a whole bunch, then not for a while, then a bunch again .. if I see a female at any LFS I go to I'll let you know.
