Not sure about if they're named but it's pooping lol.

I thought is popping but only that one. Others not...

It probably caught small piece of food while the others didn't. See it regularly in our zoas ones that actually catch food will pooping ones that don't n feed off lighting won't. Yet it's all the same colony n all appear the same and healthy.
