Hello everyone.

I'm seriously considering setting up a tank for Peacocks and I've been pouring over many of your different threads soaking up as much info as possible. Many of you have some beautiful setups and I'm truly envious.

My question is: Where do you find some of these large pieces of rock to use as decoration? I'm no expert about rock, do you use slate, limestone, shale??
If shale were ok, I'm set. I've got access to tons of shale. It's free, so I'm sure it's no good for an aquarium. LOL

My LFS is little to no help, they are very small and limited in supply. I can drive to some of the chain stores but they don't seem to have much either.
Any help or pointers would be greatly appreciated.
