I actually got it for free, I was at the tail end of my cycle on the tank. And my from grows and sells corals, and he have me it to see how it did it my system. I think the little frags go for $15-$20. That piece he gave me was probably a $35 frag was a little bigger than the normal ones. I was trying to sell this for $80, but no one where I live ever really responded. Lol I might have some cheap friends
