The Look Down Fish, Selene vomer,  has one of the most unique body shapes, featuring a shiny body and a blunt head. They should be kept in large tanks, preferably as a group of three or more, with plenty of space to swim freely. They are intense schooling fish that require a completely different tank set up than the typical reef tank. Little live rock should be present, and there should be a sandy substrate. The Look Down Fish will eat a varied carnivorous diet. These Look Down Fish are captive bred making them even more suited to thriving in the home aquarium.
