It must have been in there when i started the tank 2 months ago with some live rock. I have never seen it until now though. i have no clams or corals of any sort just 200lbs of live rock.
It was right by that margarita snail which is now dead??
I cannot imagine how I lost it. I watched it go right under the rock and just minutes later I could not find it.
thanks for the help. I was in shock and should have scooped it up first then asked questions
