Depends on how rare they are and how bright. Some LFSs sell for a $1 a polyp, but that is a expensive IMO. Its up to you! Your corals! I guess you just have to feel out the crowd.:thrash:
I'll pass on the purple ones I saw some recently on a website and thought they might be the same ones. As far how many polyps are resonable for a sale I have bought frags that have had 5,10 and 20.
how many are reasonable well lets see i think 100 for $ 20 is good lol , j/k , its reallt up to you what ever you feel is good. Ether way I would like 2 frags and would you ship ? Idk when I can come to brooklyn.
