Help with id. Possible nudibranch?

Found this in my little hang on refugium. I'm guessing a nudibranch. Seems to be eating algae. Must have come in with GARF grunge or the cheato they included with my order.

"lettuce slug" I will work on ID, maybe Elysia Clarki a "false" Nudibranch (not actual term they just aren't nudis but people get confused) that eats algae and uses the chlorophyll to produce energy

edit 1: can you get a closer picture? I think maybe its Elysia Chlorotica

I'll try to get a better picture tonight. It's more round than elongated. It's almost flat that bulges slightly in the center.

elysia chlorotica

elysia clarki

they are both lettuce slugs, the most common in the hobby is the elysia crispata

Thank you!

Elysia chlorotica looks to be a close match in shape. The back looks to be more spotted like the clarki.
I love finding little critters in reef tanks! Well as long as they're good critters.

they are good in tanks! with proper care this guy can live 2-3 years, as he gets older he might eat less and frequent sunny areas, in addition, their foot isn't super tough, so screen off power-heads maybe (most guards they come with work fine too
