The Blind dartish is a fish located in deep waters, so deep and dark that its actually born blind. It sense motions and its environment with the tendrils on its sides, which are attuned to the motions and currents in the water. Its a fish that consumes bacteria and much smaller fish through its long nose/mouth. The tail til on it produces a pheromone that helps attract other blind dartish so they can swarm together in schools, as this is only just the baby form of the blind dartish, and is rather helpless. The pheromone is only recievable to other blind dartish, much like every other creature of the world.
