I have a zoa frag that doesnt want to open very much. It has these 3 black encrusted things growing near them. They seem to have 2 little antennae sticking out at times. Are these vermintide snails/worms? If yes what is my best option, pull the frag out and break these guys off? Crazy glue them? I assume this is also the reason these zoas dont want to open?
Thanks!
Thanks!
