These are very cute little fishies (just look at that happy-go-lucky face in the first pic!) called Western Cleaner-clingfish (Cochleoceps bicolor)

They’re found among sponges but come out to help the neighbors with their chores… more specifically, their personal hygiene problems. These lovely fish will give their friends a thorough cleaning while simultaneously feasting on one of their favorite foods: parasites. Hey, to each their own right?
