General info about Upside Down Catfish
The average adult is 4 inches. This species is adapted to spend its time upside-down, as it ages it spends more and more time in this position. This adaption has consequences on its coloration; the belly is darker than the dorsal area of the body working as camouflage against predators above. To keep Synodontis nigriventris in captivity the water should be between 71.6ºF and 82.4ºF, the aquarium should be dimly lit, have a soft substrate and plenty of hiding places where it can get some refuge, these fish like to have its belly pressed up against a surface, so it is advisable to have some bogwood and branches. This species is peaceful and can be kept in a community aquarium as long as none of its tankmates is a potential predator or prey. It is advisable to keep it in groups of at least 3, it can be kept as a single specimen, but the individual will spend most of its time hiding and won’t be active at all, a group of 2 isn’t recommended because one will dominate the other through constant aggression.

However, it is known that they lay their eggs in depressions in the substrate or caves, that there is no parental care, that the parents will eat their fry and that the fry starts swimming upside-down after 7-8 weeks.
Upside Down Catfish Origin
This species can be found in Congo and Cameroon, Africa. It inhabits densely vegetated riverbanks.
Caution with Upside Down Catfish
