Catfish vs Bullhead
The main difference between Catfish and Bullhead is that Catfish is slimmer in appearance and has a narrower mouth, whereas, Bullhead has a flat and broad head and compact body. Catfish can reach around 25 pounds in weight, while the bullhead cannot even go up to half of its measure. Catfish are also way longer with a tail that has a deep split, while the bullheads have a squared-off tail.
Catfish are sleeker in appearance, having a split tail. They range from brown to blue in the colour of their backs, and the stomach part is silver-white.

Also, they are found in freshwater. However, they like to stay more in shallow, running water bodies. They come in various body shapes and sizes, although the flattened head is common.
The fishes have a narrow mouth that can expand when required. They usually gulp their food instead of cutting orbiting it. They are omnivores and feed on insects, seaweed, small fishes etc. Including their deep split tail, the body length can reach up to 20 inches, which is considered one of the longest of sizes among bony fishes. In terms of body weight, catfish rarely exceed 100kg. There have been instances of very heavy catfish getting caught for real.

Bullheads are found all around the central parts of the United States. Stagnant or slow-paced water having soft bottoms are their primary habitats. They assemble in confined spaces, especially under dams. They are very tolerant and can also adjust to low oxygen levels. Large parts of Europe are inhabited by these fishes. Being omnivorous, they feed upon seaweed, crustaceans, snails etc.
Bullheads have an interesting hibernation technique which they practice to survive in low temperatures. When the winter arrives, they decrease their food intake or stop eating and bury themselves near the shoreline.
