What kinda NUDIBRANCH is this? How BAD is this??

[ChuckTownReefer]

Found this nudi just walking around on the side of the tank. I have put Berghia nudibranch in the system like 7 months ago but it really doesn't have the same colors as a Berghia nudibranch does. This one has red and a brownish body.

I don't see any bit marks on anything just went through and looked at pretty much everything.

Just looking for some advice on what this nudi is eating on so I can deal with it. Any input is welcome!

The advice I got when finding hitchhiker nudibranches was: if it's colorful it's probably eating coral. Wish I could help with ID and verifying its diet!

Any chance you could get pics of it under white light? The pics are kind of dark and blue.

Nudibranchs look so cool and this one is no exception; rooting for a good one

Most of the nudibranchs I've seen were the zoanthid eating type. So if you have zoanthids, maybe,,,,
So with this type, if you see one, there probably will be others and eggs.
Not good if you like zoanthids.
I've also seen the type that eat leather corals, again maybe,,,,

I have also had berghias. That doesn't look like any I've had.

I have not seen any that don't eat some type of coral.

So when in doubt,,,,

if theres no coral irritation or damage, this could just be individual that has gained the colors of your strain of pest nems. its a little hard to say. I would recommend keeping a very close eye on your corals, particularly zoas if you have them. Make sure to look out for more individuals particularly around the base of corals too, they will likely be camouflaged
