What is this on my Zoa frag

[awais98]

I found this on my closed Zoa frag, I manage to suck it out with a long pipette syringe.
That Zoa was closed today so I was wondering what happened. And I saw this guys appendage glowing on the actinic light and got it.
Nudibrach? Harmful?
Here is a pic and a video.

Looks like a nudibranch. Google "zoa eating nudibranch" to find a bunch of threads on how to try to get rid of them. From what I read they are definitely harmful to zoas, thus the name.

Use Bayer.

I would Dip all your Zoanthids.

Check for Eggs too.

Dips will not kill eggs.

These creatures will Kill off All your Zoanthids.

Luckily they will not bother any other Coral though.

I recently did the Bayer dip and it was great; actually killed ones of these. Just remember that stuff is nasty so make sure you wear gloves.

+1 on this.

I would dip them every 4-5 days for about 2 maybe 3 weeks just to get the babies that hatch from the eggs you might miss. These can multiply very quickly so dip dip dip!
