Sorry for this crappy photo. The rock is about 5x5x6" and covered with zoos:
If someone wants a nice full colony of zoos, here it is. I would take a piece of mature live rock (and some cash) in trade.
If there's enough interest I could also break it up into maybe 4-5 pieces.
Here's a close-up shot of the polyps:
These zoos have never hurt me, I just need some room and options for the new tank.
