38 Curly Cue Anemone (Aiptasia family)

Much debate whether these guys are good or bad for your tank. There is an aiptasia which is also known as "glas anemone" that orignates out of the pacific. When people attempt to kill them by remove or pullin on them, they shatter and replicate massively taking over your whole tank.  Not sure the Curly Cue is as prolific and spreading, but if you do remove them, use Joes Juice and inject the mouth or the stalk.  I have 5 which i have not touched in my tank. They have not spread but have grown. I havent tried to pull them out yet either. The curly cue looks darker than the typical INDO glass anemone which is known as a pest. Though same family genus, I think they are quiet different animals
