looks like a sponge. good thing

 

[Mattchamp]

I doubt it is a sponge, it showed up out of nowhere and it wasn't there yesterday I think its a nudibranch it looks like one but could it?

 

[Russellaqua]

I'm not positive but I lean towards nudi.

 

[Mattchamp]

But are nudi's nocturnal? Because this guy did not move all day

 

[Connie]

It's a nudi

 

[Mattchamp]

Thanks everyone today it moved and I found it 2 inches from its original spot so I'm certain it's a nudibranch

it is tritoniopsis elegans what do they eat? sponges, algae? can I sustain it?

 

[User Name]

Eats soft corals as far as i know. I suggest removal.

 

[Mattchamp]

I do have a cauliflower coral that is dying maybe it feeds on it? Removable is probably not possible also could I farm the cauliflower as a continual food source?

You are above my knowledge at this point, when it comes to soft corals. I keep sps corals in one tank and a separate much smaller hitchhiking crab tank. Hopefully someone with more experience with soft corals can answer this one. If you would keep the nudi, the only thing i would suggest is maybe stock up on more soft corals and hopefully that will keep the nudi feed while allowing them to recover at the same time.

I'd say you got it. Another really good identification site is: nudipixel.net
Almost every nudibranch is not a good thing.

I vote for Tritoniopsis elegans.
