Wow, you guys love these things huh? I think I replied to everyone that PM'ed me.
They are still not out yet and they are not taking the bait. Here is a little more info for those interested.
The red guy seems to be the most active out of them all and started showing all of himself today for the first time. By active, I mean he actually comes out of the rock instead of just peeking out like the other 2. He has actually burrowed all of the sand out from under one side of the big rock and I am scared he might crack the bottom glass. He hits alot.
The other 2 guys, one I knew about when I first posted this does seem to be in the same size range as the red one. They both live in the same rock and the rock is big at 32lbs. Its ackward to get out of the tank so I am trying to avoid that if possible but if I have to remove it to get some club soda in there to chase these guys out I will this weekend.
The 3rd one I found today is in another piece of rock but it doesnt look to be as big as the first 2 maybe around 1.5" - 2" he is also the brown/blue color.
When I get them out I will take pics and post them for all to see.
