+1 on the nudi id. Definitely has the looks of some form of sea slug/hare. To be more specific, it could be the species diversidoris crocea, or a yellow caulerpa slug

I haven’t added any new rock or coral to my tank in months but today I noticed a bright yellow nudibranch about 2cm long moving across the back glass of my aquarium. The back of the tank is rarely cleaned so it wasn’t easy to photograph it through the algae buildup but here are the vest photos I...

general consensus indicates this COULD be an "elysia sp."
