Behavior
Redtail catfish are territorial. If given enough room they are peaceful with the occupants with them in the area, but because of their size they will eat smaller fish.
Reproduction
Catfish have an interesting breeding routine. After bumping the male on the vent, the female receives the sperm into her mouth. She then discharges a few eggs which she catches and clasps with her ventral fins. Then she deposits the sperm on the eggs at selected spots.
Wild Diet
It feeds heavily on live and dead fishes and other meat. Even as a juvenile of only a few inches in length, they are able to swallow many of the more common aquarium fish such as tetras. They also will eat crabs and other crustaceans.
