ID neon green spiked snail/ slug?

[TapoutBullies]

ID please! I don't know if I should flush or keep? He crawled off of that Zoa plug.

 

[Carter o51]

Nudibranch. Likely zoanthid eating if he came off the plug. Remove it and inspect any zoas you have for eggs or more of them

 

[Tahoe61]

Yup, he wants the green zoanthids over yonder.

 

[mfinn]

Zoanthid eating nudibranch and he's looking for a new colony to eat.

 

[TapoutBullies]

I pulled him out immediately! What are my odds of there being more? I blew off all of my other colonies and didnt see any others. Should I treat anything?

 

[mfinn]

Most likely there will be more, and very good chance there might be eggs.
Is the plug that is closed up something new to the tank?

 

[TapoutBullies]

Sort of new. Like 3 weeks.

So... I have had these...there's never just 1....
Pull all your zoas and any other rock with corals on it and dip in revive or another coral 'cleaner'
I used Saliferts flatworm exit at 1 drop per gallon, repeated 2 days later, then repeated in another 6 days (the length it takes for eggs to hatch) and you can do another round if you see any again...
But many have cautioned about the FwE and it has possibly caused tank crashes....

 

[Carter o51]

It only can cause crashes if there is a huge flatworm die off from infestation. It won't do anything bad if the tank isn't overrun with flatworms

 

[TapoutBullies]

****. Luckily I have mostly frags. If I pull them out and dip them separately will the risk of a tank crash go down? I honestly did just find another tho. :-(

 

[Small triggers]

I don't think you'll have a crash...I have a 150g and I pulled every coral I could, dipped them, then did the FWE treatment...I did keep a 20% batch of water made up just incase....
If you've only seen a few, just get a jump on them and dip everything you can...because even though they might only eat zoas...they will lay their eggs on ANYTHING....so dip everything you can...use a toothbrush to scrub off anything that looks like eggs on your rocks or frag plugs that you pull...they do not come off easily...

You need to start dipping.
Here is one method I use every time I get new zoanthids.

This doesn't kill eggs.

However there is another dip that claims it will kill eggs.
Maybe get some for the future.
I'd start off right away with the FWE.

Having zoanthid eating nudibranchs won't crash your tank, they will just kill all the zoanthids.
You need to do something very soon. The longer you wait the more nudibranchs will hatch ( where there are nudibranchs, the chance of eggs are high)

So to follow up. I ended up trying CoralRx. I pulled every coral for one big dip. So far I haven't seen any and all colonys look great! Thanks everyone for your input and advice! Very much appreciated!

Cool, but keep watching. There may have been eggs that you missed.
