Help ID anemone-like critter

Kingston · Jun 20, 2022

Just found this growing on this rock. Rock has been in my tank for almost a year.

Really hard to tell with a the blue... Is there any real live rock (like from the Gulf) in the tank?

Mojano possibly, but hard to tell form the video and pic.

Sorry for the poor quality pic. I was feeding just before light goes off and saw this. I will post a pic in better light tomorrow. Yes I have a few rocks from gulf live rock just a year ago

Doesn't look like typical aptasia.

On the gulf live rock web site, he has a picture of something called light bulb anemone, not sure if that is what it is and whether it is safe or not.

Probably majano then. Definitely a pest anemone.

Could be that or a curlicue. If you've had the rock for a year and you're just now seeing a single anemone, regardless of the type it clearly is not a rapid spreader! I have a single aiptasia that's been in one of my tanks for over 2 years... Have never seen another.

If it's pretty and you like it, consider it a nice belated surprise hitchhiker.

"Safe" is a relative term. Carpet nems will eat fish but people buy them all the time...

I would say definitely NOT a pest if nothing has been added in a year and there is a total of ONE mystery anemone...

I don't believe this is correct, at least not from the photos of lightbulb nems I have seen. Their tentacles are longer than majanos and they get bigger.
