I'm so afraid to venture into buying things online... I just bought my first frag (pink zoas) online from another hobbyist who is dividing a huge colony and I'm anxious to see how they're shipped and what condition they arrive in. If they're fine I imagine I'll feel more inclined to buy things online, I just have trouble buying things sight unseen and knowing they'll be bagged and travelling for long periods of time, possibly sitting on a loading dock somewhere waiting for border clearence, and handled by clueless postal guys who don't understand how to handle livestock. I do feel it's more responsible to leave things in the ocean and buy tank-raised stock, and if I ever switch my 65g to marine (hmmm...) or lose one of my current fish I will go with captive-raised animals.
So... I had planned to return the emerald... my husband and I got ready, and I figured I'd entice him with food (he's trained to take food from the dip tube, comes running when it enters the water) and just pluck him off the rocks. Um... wrong. He's like velcro! I didn't want to pull him too hard and injure him, so I ended up letting him go. Of course, he's no dummy and scuttled off under the rocks where I can't reach him. I'm not going to dismantle the tank and upset the new corals, so unless he comes out again some time this afternoon I guess he lives with us for a while longer.
[edit]Since I was in the tank trying to catch the crab, I couldn't waste the opportunity to mess around with things a bit... I accidentally moved the polyps' rock trying to catch the crab and couldn't get it to stay in place, so it's been moved a bit. I found that both the polyps and Xenia didn't seem to like the amount/type of flow they were getting from the PH (too direct I think) so I moved it and attached a little diffuser doohickey; everyone looks more relaxed now.
The wrasse disappeared for a while tonight, right after dinner. I couldn't figure out where she was, and then realized she'd gone down to patrol the pistol's tunnels, looking for food bits! He's got the entire tank dug out under the rocks in such a way that the current blows food right into one entrance. I guess it's taken a while, but the fish have figured this out! Here's a pic of Gwynnie (that's right, since there are only two fish I've named 'em - the goby's name is Bert

) coming out of the tunnels:
