Coral Or Something Worse?
Hi all, I put this live rock in the tank to start the cycle on Saturday and yesterday noticed 2 of these little guys coming out when the lights go on. I gave the rocks a quick rinse in water before putting it in the tank and lots of worms came out, but didn't see these until yesterday. They don't look like aiptasia so I'm hoping it's just a frag of a coral that is stuck on the rock. Has anyone seen this or know what it is? Thanks in advance.
