I think they are zoo's but not too sure..
as we will be getting a peppermint shrimp to kill our glass anemones and just want to know if they will munch there way on to these nice things in our tank..
:notsure:
those are button polyps.Your peppermint may or may not eat them.with those type of shrimp it is a hit or miss.some will eat polyps and some wont.my 2 cents
