Nah, it's neither, it's an elysiid, and judging by the bright colors, streamlined appearance, and large rhinophores, it's probably a species of Thuridilla. There are a couple of Thuridilla species that are pretty close in coloration, but I don't know of one that's an exact match...maybe because it would look somewhat different if it were adult. It will be an algae eater, in any case.
Cheers,

Thanks! Yup looking at other pictures it looks like Thuridilla. And it was definitely chowing down on algae.
