Sounds like some type of Sea Slug to me. How many is "Several" cones on its back? We might be able to narrow it down to an "Order" but for a Genus/Species you're going to have to provide a picture.

Okay I took a closer look at him. His top side seems to be purple and the "cones" seem to be white. It is hard to count when he is moving and since he is very small be he has at least 20 "cones" and he as a set of "horns" or atenna on his head. So you have any ideas on which one this could be?

Probably what Ophiura suggested. Some type of Nudibranch.
