The Tetra is a small [Exotic] teal and pink fish that swims in groups. The game says that they fear the Bagu, because they are its prey. It can be caught with the small bait during the day on the medium water depth. It can be sold for $4,800 if it stays uneaten.
In-game description: Tetra swim in large schools, covering a large swath of the sea as they evade the beligerent Bagu.
