Please help to id this slug thing hitchhiker

Found these yellow slugs today. They have sorta like cauliflower "eye stalks". Are they a danger to my corals?

Can't see clearly from the pic. Does it look like this? If it does then it's a yellow sea cucumber. A rarely move filter feeder

It does move around a fair bit.. So maybe its Elysia flava? Does looks similar.
