How long do catfish carry their babies?

Answer 1

They don't carry their young. Catfish, like most fish, lay eggs that are fertilized outside the body.

Catfish males, however, make a nest, and watch over a fertilized clutch of eggs for their 6 to 10 days of incubation, deterring predators and stirring the water to improve oxygen going to the eggs. After the eggs hatch, he will continue to watch over the hatchlings for several days until they swim away.
