I just bought some Florida Live rock. I was told not to, but I am a you live you learn person. I bought it with the hopes I would get one of their nasty little mantises. I didn't though, I ended up with a neat looking little lobster in one of the larger pieces and 2 red pistol shrimp. I also got a few rock crabs, but I wanted them because I have a tank set up and am waiting patiently for my peacock mantis. I have heard that there will be stuff coming out of live rock for months, but most of the live rock I have bought before this batch was from the caribean and was freebie free minus a few brittle stars. The Florida Live rock is already growing some facinating sponges and trunicates, so I can't wait to see what else is in store for me.
