Is this a tube anemone? He emerged from my live rock. I'd like to know what it is, so I can properly care for it. It's in a 55 gal tank with a yellow belly damsel & 2 oscellaris clownfish.
It has a blue center. I'm disappointed if it's a pestYou don't want to care for that one! Looks like you've got aiptasia. It's considered a pest but usually if you find one you've probably got more. They reproduce quickly and can sting corals.
It's not fully cycled yet, no nitrates, ammonia bet 0 & 0.25 ppm & nitrites at .25. My clowns & damsel are doing great.It could also be a majano anemone also. Both are a nuisance. Good luck with you tank. Did you cycle the tank?
