Redtail Catfish
The Redtail Catfish has a broad head and body that tapers towards the tail. It has a dark black body, white underbelly, and a bright red tail.
This fish can grow quite large in an aquarium and requires ample space to swim. A minimum tank size of 300 gallons is recommended. Due to its size and active nature, it should be kept with larger, compatible tank mates.
To create a natural environment, include rocks, plants, and large driftwood. A tightly covered tank is essential to prevent jumping, as the fish is highly active. It matures into a heavy fish and should be housed in a reinforced aquarium.

The Redtail Catfish is a striking addition to my 300-gallon tank. It moves around a lot and adds energy to the environment. I made sure to include plenty of driftwood and plants for hiding spots. It’s active but stays calm in its space. Only kept with larger fish, as recommended.

Great fish with a vivid red tail. It’s not shy and enjoys swimming in open areas. I added a tight lid because it tried to jump a few times. The tank setup with rocks and plants works well for it.

After a few months, the Redtail Catfish has grown significantly. I had to reinforce the tank to handle its weight. It’s a beautiful fish and very active, especially during the day. The white underbelly contrasts well with the dark body.
