Let’s take a closer look at the key points related to feeding your red tail catfish.

What To Feed Your Red Tail Catfish

The red tail catfish is a predatory fish, and it is essential to provide them with a diet that replicates their natural food sources. It is best to feed them a diet that is high in protein.

  • Pellets and sticks designed specifically for carnivorous fish that contain 40-60% protein

  • Crickets
  • Small fish such as guppies or goldfish

How Much To Feed Your Red Tail Catfish

It is important not to overfeed your red tail catfish as they can easily become obese. Overfeeding can also lead to various health problems such as swim bladder disease. You should feed them an amount of food that they can consume within 2-3 minutes.

As a general guideline, feeding them one percent of their body weight, such as ten pellets per five pounds of body weight, is sufficient.

Feeding Frequency For Your Red Tail Catfish

Most adult red tail catfish require feeding once a day. However, you may need to adjust the frequency based on the size and age of your fish. Younger fish may require feeding twice a day in smaller quantities, while older fish usually eat less.

It is also a good idea to vary the feeding schedule throughout the week to mimic their natural feeding patterns.

Proper Feeding Techniques For Your Red Tail Catfish

To ensure that your red tail catfish eat correctly and reduce wastage, you should:

  • Break up or crush large pellets so that they fit in the catfish’s mouth
  • Feed only what they can consume within 2-3 minutes
  • Observe your catfish to ensure that they eat during feeding times.
  • Remove any uneaten food from the tank to prevent fouling the water
  • Avoid commonly used feeder fish such as goldfish, as they can transmit diseases or parasites to your red tail catfish.
