Origins of the Adolfos Catfish

Adolfo's catfish originate from the clean and fresh blackwater creeks and areas of flooded forest where the water is stained dark in colour with organic chemicals in Brazil, Trinidad, Rio Negro and Rio Uaupes of South America.


Adolfo's catfish will eat all types of food, and they should have a diversified diet of frozen, live and artificial foods. Sinking pellets and bottom feeder tablets are recommended as they are bottom dwellers.

Also make regular vegetable additions such as cucumber, poached or boiled spinach and peas, make sure you remove uneaten foods at night.

Sexing the Adolfos Catfish

In Adolfo's catfish, the different sexes are quite evident.

The female is more rounded, broader and higher, and has rounded dorsal and pelvic fins, unlike the male where the fins are more pointed, and they are shorter.

Breeding the Adolfos Catfish

Adolfo's catfish are easy to breed with the correct water parameters.

Two males per female are advisable if possible into a well-oxygenated tank. Make sure there is plenty of plants, and leaf vegetation as the female will stick her eggs to them as well as on the glass and stones available.

Add Some slightly decomposed Indian Almond leaves or other leaf litter on the bottom of the aquarium if you are going to leave the eggs in the tank for hatching.

Once the eggs have been laid and hatched its advisable to remove the adults as they will most likely eat them.
