When we did that bullhead eradication get-together, mentioned by catmandoo, their guts were filled with filamentous algae.

It made us think they were trying to eat something that was in the FA, and just ingested a ton of it during the process.

When I fish with live minnows or shiners, I will catch bullheads.

So, they eat a lot of different things.

Cody Note: FA generally has myriads of small invertebrates mixed in with it - most of them microscopic - protozoa to insect larvae. With all the animal life in FA there is likely nutrition in and amongst it.

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
