Largest Polyp Diameter Zoos Available?

[sahmof2]

I have seen pictures of reef tanks with large polyp corals that look like zoos. Some said monster zoos for name. I currently have 5 varieties of zoos with polyp diameters under 7mm. I want to find easy to moderate care zoos with polyp diameters 15mm or greater.

Yup, many Palythoa are greater in diametr when compared to your normal Zoa.
