What hitchiker is this?

[253Gixxer]

Hello All,

I’m pretty new in this hobby. My tank has only been up and running for about 10 months now. I need help identifying this hitchhiker. I tried researching this but couldn’t find anything conclusive. They look like little orange snails with no shell. Don’t know if they’re good or bad. For now, I’ve been removing them using a turkey baster. I’m a subscriber to when in doubt take it out. If they’re bad, what’s the most effective ways to eliminate them? Thanks for helping a newbie out!

The closest I could find was an Elysia, @Lionfish Lair 's hitchhiker's guide https://www.lionfishlair.com/hitchhikers-guide/

It looks orange in your picture, and green in hers, but the shapes are very similar

Looks like a calurpa slug or Elisa crispata. Usually herbivores.

Type of sea slug. Can you get a better picture, hard to tell without detail. Sea slugs tend to eat what they look like, some orange ones are sponge eaters.
If its not a coral eater the issue arrises that it might starve and many are toxic.

If cant get a clear picture theres a forum just for sea slugs.

Looks like a nudi, I would separate them from the tank, since they have a large family, we don't know if this is reef friendly or killer

I have a few small orange ones. @KJ identified them as one that eats the spirornoid worms
