Fish (High Ground habitat)
From Halopedia, the Halo wiki
A species of fish native to Earth.
On the level High Ground, one can find small fish in the water. It is possible to kill them; if you do, they float to the surface and then drift to shore before eventually respawning. Throwing a grenade in the water will result in the whole school dying and floating to the surface (like throwing dynamite in a pond).
