Can I keep this nudi?

[MmeAssoc]

Just spotted this guy crawling over my GSP - can I keep him, or does he need to go?

I've noticed my zoas have been looking very unhappy this week - any chance he's been eating them?

I don't know much about nudi's, but I'd say that the fact that it's fairly colorful (getting its color from its food) and the fact that it's hanging around your corals is probably a bad sign. I'm sure that more knowledgeable reefers will chime in, but If it was me, I'd pull it out if you can get to it.

I think you're probably right, unfortunately! Nudis are one of my favourite things to spot when diving, so I'd love to keep him in the tank - but the zoas sudden downturn is very suspicious.

Hard to tell species....but when isn't it with Nudi's .... the percentage of one's that are helpful or peaceful vs those that aren't? I would pull it stat. And agree when diving, a fun find for certain!

It’s cerata tells me coral muncher.

 

[Rmckoy]

What ever coral it’s on . It’s eating it . And that’s it primary food source .

when the food is gone , so will The nudi

It’s cerata tells me coral muncher.

Because they look a bit like coral polyps?

 

[vetteguy53081]

I would not as there are very few Nudi's that are safe and being unidentified is a warning sign

 

[Zoa_Fanatic]

Because they look a bit like coral polyps?

Yes. Camouflage. Kill it with fire

 

[Redfoxtang]

When in doubt pull it out!

Yes. Most cerata take the form of their food source, one to use as defense and also to blend in with their environment. It's not always the case with nudibranchs, but for the coral munchers, it's pretty common, especially with soft coral eaters. Here's a good resource for nudi ID Sea Slug Species List

Thank you, that's really useful!

I have reluctantly banished the nudi from the tank

It’s funny, when I started in this hobby in the 80’s, we used to get really excited when we discovered new things in our tanks. It didn’t matter if they were good or bad, it was just something new and we welcomed pretty much everything. It was a journey of discovery. Nowadays, I think new hobbyists miss out on that excitement and think everything is bad. Granted, we don’t want certain pests in our tanks, but there’s kind of a flamethrower mentality to new unknown animals.
I used to watch my display refugium just as much as my display just to see what new critters that would emerge seemingly out of nowhere. Good times, good times…….

I think the excitement is still there, just tempered with the knowledge that reefers before us have gained - I was definitely thrilled to see a nudi in the tank! Although I'm quite excited to see even an aptasia in the tank - there's something exciting about seeing lifeforms you haven't introduced thriving anyway. It makes me feel like, at least I've created a space that isn't toxic to life!

But I'm glad I have the benefit of the knowledge that reefers before me have gained. My mystery nudi might have been beautiful and interesting, but odds are it was eating my coral and those frags are expensive so it had to go!

Absolutely, we now know what’s good and bad for the most part. I think nudibranchs are super cool creatures, but 99% of them don’t belong in our little slice of the ocean and need to be removed, I was just reminiscing about the good ole days. Happy reefing!
