Please help to identify

[micah]

Hi all,

I have a 70 gallon sw setup and I have noticed in the past month that i have been getting these little jelly fish type of things. They start off by growing like little white polyps on my rock and then detach and swim like jellyfish around my tank. They are about 2 or 3 mm across.

I am struggling to get an image of them free swimming but I think that i have got an ok one of them on my rock. They are the little (aloost transpartent things that are all over my liverock.

Can anyone pleae help me to id them?

Thanks,
Micah

It looks like teh jellyfish to me. Is there a way to get rid of them?

Those are Aiptasia or Mojano anemones. They are a pest anemone that can populate out of control. There are chemicals you can use to rid them or I prefer to add a Raccoon butterfly to do the job. Once the anemones are gone remove him and trade him back to your LFS. Good luck!

I thought that they may be Aiptasia or Mojano anemones as well but what confused me ius that the top eventually detatches and then swims around the tank like a jellyfish. Would an anemone do this?

[Rastapus]

Do they move around independently by propulsion or just moving with the current?

[Rastapus]

They could be a form of Jellyfish or Hydra, they would need very high nutrients to survive like this. Interesting. Please give more details.....

[micah]

It seems to move with the current as it is so light. The body it self though pumps like a little jelly fish though. Are jellyfish or Hydra generaklly safe to have in the tank. . Do they piose health risks to me?

Thanks so much for your help
