Can anyone ID this growth

Actually, those are a variety of hydroids.

Which ones are you referring too?

There are way too many species of hydroids to actually give them a name. I never try to ID that specially.

Oh sorry I meant in the picture, are you saying they are not aptasia but instead hydroids? Or are you talking about the thing with a mouth that appears to be some type of filter feeder?

 

[Lionfish Lair]

LOL! Gotchha...

That's a photosynthetic hydroid that my arrow is pointing to.

Ok thanks,

So are they good/bad and if they are bad how do I remove them?

 

[Lionfish Lair]

Are they only on the frag? If yes, take it out and @twilliard can tell you what to use.

These aren't good, no. They can be a pain if they get everywhere.

We used to call those pom pom hydroids and includes a few different species. One type is Myrionema. They are different than the "regular" hydroids in that they have color due to the tissues that make them photosynthetic.

If it's a frag, I would remove it.
