As a general rule they will do fine if kept within the following ranges, Temperature: 72o to 79o , pH:6.2 to 7.8 and a dH of 4o to 25o. The tank can be decorated with driftwood and a few live plants, soft sandy substrate is essential to prevent damage to the barbals. The water should be well aerated and filtered and changed at regular intervals. The Armored catfish are Omnivorous and should be fed a varied diet.

    Sexually mature specimens are easy to tell apart, the females have a stouter body and the males has a larger and more pointed Dorsal fin. You should have a ratio of two males to each female. Courtship consists of the male touching the female with his snout and then the female will swim constantly around cleaning rocks or plant leaves in the tank. Then a male will grab the females barbals and twist his body into hers and she will release her egg pouches at the same time as the male sperm. This is repeated several times with the female taking the egg pouches and placing them at various locations throughout the tank. After spawning you can remove the parents from the tank. The eggs will hatch in about five to eight days and the young are not hard to raise and can be fed fine flake food or newly hatched brine shrimp (fresh or frozen). Growth is fairly rapid given proper conditions.
