I've never noticed any fish missing in my 75, but I do remember finding a claw with black tips once. Over time I had moved a few rocks down to the sump b/c the display was a little crowded.
So I got a nano a few weeks ago, and moved some rock from my sump to the nano. Low and behold last night while I was sitting at my computer I noticed something moving out of the corner of my eye. It was a little crab coming out of his bunker.
I turned off the lights and got out a flashlight...yep, a gorrila crab. He doesn't come out much, but I think I'll keep him for the time being. How big can they get? I put a piece of shrimp in the tank last night hoping he'd eat it.
There are no fish in my nano, so I guess he won't be a problem? Do they mess with coral? He looks to be the size of a half dollar...
