The breeding tank should be at least 30 gallons in size and should have a water temperature of 78°-82° Fahrenheit. The grow-out tank can be any size and should have a water temperature of 76°-80° Fahrenheit.
- Collecting them from the wild: This is the most difficult way to breed them. To do so, you must collect a male and female Upside Down Catfish from the wild. This can be done by setting up a trap in an area where they are known to live.
