Choosing the right catfish for your tank
Always check the adult size, because catfish vary more than almost any other group. Corydoras and small plecos fit 20 gallon tanks, medium species like pictus and Synodontis want 40 to 55 gallons, and large catfish such as redtails grow to several feet and need enormous aquariums. Most are comfortable at 72 to 80°F with a pH near neutral, and all appreciate hiding places like driftwood and caves.
Use sand or smooth gravel to protect delicate barbels, and remember that catfish are not garbage disposals. Feed sinking wafers, pellets, and frozen foods, ideally after lights out since many catfish are nocturnal. Most are peaceful, but large predatory species will eat any fish that fits in their mouth.
