Hi just revived my mail order frags and found this in the bag, looks like a tiny star fish but I am new to this, anyone shed any light before they go in my tank
I've got a blue ish colored one (presumably more than one) in my tank. Guy who I got a Zoa rock from had tons of them, and said he had noticed some munching on zoas. If you can, I would eliminate now before it becomes a problem
