What Is It?

The brown bullhead is a small, tough catfish with a flat head, whiskers (“barbels”), and a slime coat that helps it slide through muddy water. It’s brown on top and light underneath—and it’s not picky about where it lives or what it eats.

Where Does It Live?

Almost anywhere. This fish is found all across the U.S., including California, and can live in warm, muddy, low-oxygen water that most other fish would hate.

What Does It Do?

It hangs out at the bottom of lakes and rivers, sniffing out food with its whiskers. It eats just about anything: insects, fish, plants, even dead stuff. You could call it the clean-up crew of the pond.

What’s the Problem?

It can overpopulate a pond
and push out native fish.

Its feeding style stirs up mud and makes water cloudy.

It’s hard to get rid of
once it moves in.

What’s Being Done to Help?

    Why Should We Care?

    Bullhead catfish help clean up leftover junk in the water, but in the wrong place, they can mess things up for other wildlife. Think of them like that one neighbor who never leaves and takes over the whole block.
