Fish (Installation 05)

A species of fish native to Delta Halo.

They can be seen at several points throughout the level Regret. It is unknown if they are related to any Earth species of fish, although this is unlikely, as they are in completely separate places.

It is assumed that they, like all species of animals on the Halos, were created or placed there by the Forerunner.

Trivia

 * In the underwater ferry in the level Regret the fish can 'swim' through the wall of the ferry, through the air inside, through the marines, through you, and through the other wall back into the ocean.
