Notable details
- Its mottled, dark-spotted chin barbels are the quickest way to tell it apart from the yellow bullhead.
- Thrives in severely polluted, low-oxygen water that would kill most other fish.
- Both parents guard the nest aggressively; the male fans the eggs with his tail to oxygenate them.
- Hunts nocturnally, using chemoreceptors on its barbels to find worms, insects, and small fish.
- Can live up to 9 years and occasionally exceeds 18 inches in large, productive lakes.
