Woohoo. I mentioned in another thread that this first shipment came with three mantis shrimp (smallish in size). I was wrong. There was a 4th. And a big one, too.
I kept hearing this click every once in a while. I wasn't sure what it was, but I had a suspicion. I thought I'd checked everything well and thought maybe, just maybe, it's the water lapping against the side of the tank. No, maybe it's a pump just making a noise. Well, to settle it, I shut down the skimmer and the pumps and waited.....
Click!
Uh huh. You know you really can't tell which direction the sound is coming from in the tank, but I had a feeling. It was coming from the big rock in the third picture. To find out, I drained about 10 gallons of tank water into a large rubbermaid tote and pulled the rock (I wanted to check how the sponges were doing anyway), submerging it in the tote. Then, I waited. A click in the tote sealed the deal. I'd found the rock.
Next question: Where in the rock?
Well, I got out my handy, dandy club soda and turkey baster, and went hunting. A little squirt here, a little squirt there. Nothing. A bigger squirt here, and there. Click! I peered into the dark hole. Nothing. Hmmmm. More club soda. Nothing.
After more than a little bit of this, I set the rock back in the tank with the side that I'd heard the clicking come from facing the front. Then, I turned out all of the lights in the room and over the tank. I waited for a couple of minutes and then shone a flashlight into the hole. Lo and behold, I thought I saw something. Something like little feathery wisps waving. So I stuck a little airline tubing into the hole and I could see it move. Found ya!
Out came the rock again. I could see he was big. Club soda wouldn't get this fella out, so I used a chopstick to drive him out. Eventually it worked.
This guy's gotta be 2 to 2-1/4 inches long. He was a bit sluggish coming out - after all, he'd been through a lot. Anyway, I set up my old 6 gallon Eclipse system for him to see if I can revive him. If so, I'll maybe see if some local aquarist or my LFS is interested in him. I'm not so sure that I am, though.
Really cool looking creature though. Let's hope he doesn't have friends or family that he's left behind in my tank!
