Fish (Fallout: New Vegas)

 are creatures found in the Mojave Wasteland. They can be seen near the crashed B-29 in Lake Mead, swimming around it. They can also be seen in the waters of Cottonwood Cove.

About
They can not be interacted with by the PC and therefore considered scenery as well as a creature, similar to the birds from Fallout 3. The one in the image is a Black Bass, seemingly left unchanged by radiation, etc.

When you ask Cass what got her into caravaning, she says she took to it like a fish in water. The Courier has the option to say "What the hell is a fish?" Then she reply that fish is like slimy lakelurk thing that didn't have claw and won't attack you.
