Wow. Those clams are not bad looking either.
They don't tell you how big they are but, with eggcrate 3 squares = approx. 2" So you can kind of get an idea of how big their stuff is.
the $20 one i got was about the size of a baseball a lil bigger then what i was exspecting, they have some i saw today that were huge tho
Mr. Coral has great prices but the disadvantage is that they sell you fresh cut specimens that haven't had a chance to heal. I had a lot of die off on their frags, making them quite small, before they healed up and started growing again. Acans in particular. Also, they messed up on a few of my frags and gave me a different frag than what I had ordered.... at least 2 or 3 (out of ~15) where NOT the frags I wanted.=/
