I will try to find some photos and posts I made a number of years ago about bullheads that had lots of filamentous algae. We culled about 150 lbs., of really big bullheads out of Pond Boss Sunil's pond in southern Pennsylvania. I took a cooler-full of them home for a father's day fish fry.
My sick brain wants me to see what is in the gut of every fish clean. Of the 100+ big bullheads I cleaned from Sunil's pond, nearly all were filled with filamentous algae, plus some fish skeletons, small snail shells, etc.
We kind of came to the conclusion that the bullheads were after the food in the filamentous algae, and not necessarily the algae itself.
My catfish eat anything that fits in their mouths.
