Sea Slug?

[Slocke]

What is this?

It’s attached to the glass like a slug. About 1/4in / <1cm in length. Appears to have 4 antennas, two forward facing, 2 adjacent to glass. And also has little yellow tufts on its back.

From the pictures it appears to be some sort of nudibranch. Not sure on the species or if it is good or bad, but many of them do eat corals. I would dispose of.

Almost looks like a tiny berghia, but very hard to tell from the pic. Any new pieces added to the tank?

Could be..?
Added a goniopora frag and some cycled dry rock
Are they good, bad, or neutral?

Thank you

+1 to this. Remove. theres quite a few nudis that look similar to berghia. Either way prob gonna starve or get torn up by a powerhead.

Berghia only eat aiptasia, so they are 100% reef safe, but we would need a close up pic to have a closer look at the cerata and overall body to identify, even then it's not 100%.

Well its disappeared now. It was very tiny so doubt I could get a better picture anyway. If it is a berghia it will have at least one aiptasia to eat
