Nudibranch need ID

[absohype]

Hi all reefers,

Anyone knows the general name or species name for this sea slug/nudibranch?
It’s in blue dotted on its back with black base body.
Curious on its diet.
Thanks

Phyllidiella species. Most likely P. pustulosa. This is a highly toxic genus of sea slugs capable of killing everything in your tank. When stressed they secrete a potent milky white toxin. They are highly specialized sponge feeders feeding on only a few species of highly toxic sponge. This is where they derive their toxin. The thing would surely starve in your tank if it doesn't nuke it first. If it were to die in the tank that would nuke it as well. Any shop selling members of this genus should be ashamed of themselves. If that thing is in your tank, get it out. Do a water change and run new carbon. Vapors from the toxin could also be potentially harmful to breathe. That thing is no joke. Here's a picture of P. pustulosa for reference.

You're welcome. Stay away from any sea slugs of that genus.
