I ordered a mixed amount of zoos from ebay it was called a frag pack. The total price with shipping was around $75. I could not believe the colors and how many polyps there were! Just letting everyone know what a good deal this was. One rock was about the size of a half dollar totally covered in zoos "probably about 30 polyps for that one rock. Every other rock had around 8 to 20 polyps. And there was also another free frag of zoos with the order. In total i got 12 different types of zoos!! The guys name on ebay is "mr.coral" - here is a link of the pack that i bought.
