If it finds itself out of water, it can survive for several hours, and is capable of walking over land to get to water. This means that it is easily observed by beachgoers in its natural range. There are a number of fish that are less adept at actual walking, such as the walking catfish. Despite being known for "walking on land", this fish ...

Some callichthyids are able to absorb air through their hind guts to move short distances on land. [4] Air stored in their digestive tracts also accounts for 75% of the necessary air for neutral buoyancy. [3] Breeding habits are also variable. Corydoradines breed over the substrate (such as rocks, logs, or leaves) as most catfish.
This long, toothy, brown-mottled fish is usually found in slow water, but can survive on land for days at a time and can even “walk” on land using its bottom fins.

[12] Flathead catfish are a benthic fish species meaning they are a fish which prefers to lay on the bottom of a body of water.
Fish are fed daily through the summer, at rates of 1-6% of body weight with pelleted floating feed. Catfish need about two pounds of feed to produce one pound of live weight. Mississippi is home to 100,000 acres (400 km 2) of catfish ponds, the largest of any state. Other states important in growing catfish include Alabama, Arkansas and ...
