Thanks - I'd say this image of the species you mentioned is very close to what I'm seeing with my eyes but can't quite capture on my phone. I'll try to get a better picture if I can yank it out of the tank for a minute tomorrow, but assuming that's the right ID, should I keep it? I have inverts and corals that I don't want eaten, but I won't remove it if it poses no threat.That's a nudibranch, probably a Dermatobranchus sp., but a top down pic of its back would be helpful for ID.
The Dermatobranchus genus is known for eating octocorals (soft corals, gorgonians, etc.) and/including GSP, so if you have softies/GSP, that’s likely a remove nudibranch.Thanks - I'd say this image of the species you mentioned is very close to what I'm seeing with my eyes but can't quite capture on my phone.

I have the same nudibranch in my tank and I’ve never put corals in there yet it has been alive for over 2 months. It has to be eating something else in order to sustain itself right?The Dermatobranchus genus is known for eating octocorals (soft corals, gorgonians, etc.) and/including GSP, so if you have softies/GSP, that’s likely a remove nudibranch.
Oh no...something that eats GSP...the horror...The Dermatobranchus genus is known for eating octocorals (soft corals, gorgonians, etc.) and/including GSP, so if you have softies/GSP, that’s likely a remove nudibranch.
Do you have any pics of it under white light (preferably straight-on, top-down pics of the slug's back and straight-on side pics both showing the full length of the slug under white light)?I have the same nudibranch in my tank and I’ve never put corals in there yet it has been alive for over 2 months.

Honestly if they didn't eat softies and gorgonians too, I'd have encouraged people to farm them by now.Oh no...something that eats GSP...the horror...
The solution we've been looking for!Oh no...something that eats GSP...the horror...
If I'm not mistaken, some nudibranch species are photosynthetic. Maybe that's what @Yotero6933's nudibranch is doing?Do you have any pics of it under white light (preferably straight-on, top-down pics of the slug's back and straight-on side pics both showing the full length of the slug under white light)?
I ask because a lot of nudibranch's (and other marine life) can look incredibly similar.
Some species (such as Berghia stephanieae) can steal some of the zooxanthellae from their prey and temporarily use them as a food source/for photosynthesis, but it is temporary. This generally only works for a few days though (for B. stephanieae, it only lasts 8 days without food containing more zooxanthellae before the zooxanthellae they've stolen die off).* So, it could delay starvation, but it's really more of an emergency supply than a permanent food source for nudibranchs.If I'm not mistaken, some nudibranch species are photosynthetic.
