slug take over?

[Jisko]

So can someone help with this please haha It started with one little guy i found and removed... now I have hundreds of what looks like sea slugs? How can I get rid of them?

What kind of fish do you have in the tank? I’m not experienced enough to know for sure, but I would bet a natural predator like possibly a wrasse would love them.

The ones on the glass in the second picture look like a form of pods to me. I could be wrong.

I wanna say a nudibranch.
But more i look into tbh can't say it with 100% certainty.

Definitely a sea slug, my guess is Oxynoe antillarum (Caulerpa eating sea slug/mollusk)

A good hitchhiker in my eyes.

Look under Elysia...

If you see them on any zoanthids, I would be concerned. Typically the algae eating ones will be more smooth like the one in the video. The ones that you took a picture of on the glass looked more frilly (with elongated nodules) could be predatory to zoathids. If they hang out on the zoathids, let us know!

They don't even go on the same rock as the zoas/palys honestly. They cover my glass and randomly on the rocks

Sounds like they are going for algae then.

Keep and eye on them but they look good to me!

Hmm, I'm going to back track a little on the specific ID and go back to a broad Elysia identification. I did a little more research. The good thing is to note that they are spending time eating off the glass and rocks focusing on algae.

If you can confirm this is what they are eating, their population will be limited by their food source. Less algae in the display will render a much lower population.

Those are Elysia. They are a good hitch hiker. They eat algae. They are nothing to be concerned about. If they really bother you I bet some wrasses would find them taste.

 

[ihavecrabs]

Much clearer photo! Very cool hitchhiker for sure.

little update... so my Hippo Tang has a love for the taste if slugs... hahahaha
