I haven't put anything new in my tank in over a year. I also got rid of all my bubble tips over 2 years ago so not sure where this guy came from. Is it an aptasia?
I still can't tell even with those pics here is a clearer one. The one in my tank has a larger base than those in the pics. Wondering if it is a bubble tip that got left behind when I sold my others. Here are a couple more pics.
I have to decided not to take the risk and get rid of it. It is in my sump on my feeder so I will take it out and hit it with a burst of fresh water from the kitchen faucet. That should take care of it.
It looks a lot like an aptasia but the stalk of aptasia are usually much longer and the attached foot is usually smaller. Not a bad call to get rid of it but I also don't see aptasia as that big a deal. Every once in a while I'll have one pop up and AptasixX knocks it right out.
Is the bottom hard, rock like. It looks like a star coral polyp common to live rock from the Carribian and surrounding areas. Google star coral and see if it looks like that.
