Good news/bad news kind of night...
The good news? The second box from liveaquaria came, the one with the sympodium. Water was ice cold and there were a number of dead hitchhiking worms in the bag, but the sympodium.... may not be a write off. I've spent the last hour warming it up and getting it into the tank. We'll see if it makes it or not. Also on the good news front the three thick stem xenias that arrived on saturday are all doing very nicely.
The bad news? When I came home I noticed that since I left for work this morning something had ripped a three inch stalk of xenia elongata right off the rest of the colony. Literally just tore it off, the gash runs 2" long by a half inch wide on the part of the stalk that remains. A bit of searching turned up the missing part.... jammed halfway down a hole leading to the pistol shrimp's burrow. I think he's my problem.
There's been other evidence that points to him, now that I'm really thinking about it. When the ricordea I bought was loose I kept finding it getting pulled into his burrows... I figured it just floated free and the current put there, it was never jammed in or anything. Then about a week ago the only ricordea that hadn't yet attached went missing. I went searching for it and eventually discovered it in the shrimp's burrow under a rock. Tried rescuing it but it was in so deeply I couldn't get it with my forceps and I reluctantly figured I couldn't rescue it. Now that I'm thinking about it I don't think it could have gotten in as deep as it was without being dragged.
So now I'm going to make a home made trap out of a small soda bottle and bait it, see if it catches anything. Fortunately I have some lose xenia at the moment courtesy of whoever ripped it apart, so I'll use that and some other food and see. I guarantee I'll have all five sexy shrimp in there by morning... but hopefully the culprit as well.
I can't for the life of me think of what else it could be. I've seen the pistol and he's definitely a pistol, not a mantis. But the hitchhiking brittle star never leaves his spot and he would have eaten the coral where it was, not dragged it off. The redspot cardinals couldn't have done it, the goby (who I haven't seen since adding him saturday) wouldn't eat coral, the pistols aren't capable of it due to their size.
