Just spotted this guy creeping across my sand bed. It's in isolation and my gut tells me to snuff it. any reactions? It is fluorescent under blue lights.

It does look like a nudibranch. Why kill it? They only eat aphasia so they are beneficial.

This particular one isn’t the same
Species that eats aptasia

but if identified properly
They generally have very specific diets and only eat one particular thing .

if you have one or more . They are eating something . And generally eating what they are found on .

For example blue velvet nudi will only eat red flatworms

berg nudi are the ones that eat aptasia
Can’t remember the exact name .

Good points. Berghia Nudibranches are the ones that I was thinking about.

Looks like a zoa eating nudibranch. Michael Vargas photography just had a pic exactly like this on Instagram.

Looks like what may be a Limapontiidae nudibranch which eats eggs and soft specimens and not a keeper
I disqualified zoa eater based on dimensions as below but again, there are several thousand zoa species which is scary
