Hey, I'm the owner of a 65g hexagon aquarium with live rock, shrimp, assorted clownfish, and green chromis. I was observing my tank one day and found something growing that sort of looks like an anenome... I purchased this tank from another aquarist several months ago and I believe he had kept coral at one point in time. Could there be some possibility if it is a growing remnant of coral/ anenome?
