Did you know...

The Sterbai corydoras is a facultative air breather, which means that they often break the surface of the water to get a breath of fresh air. This is because they have a very vascularized intestine, which makes it necessary for them to inhale oxygen in the air.

These fish are aquarium safe and can thrive in a tank environment. The tank size should be medium to large, have a water pH in the range of 6.0-7.6, and cool temperatures in the range of 73-79 F (22.7-26.1 C). They also require sandy bottoms as they are bottom dwellers and should also have rocks, branches and plants.

They are easy to take care of, and they require only occasional water change. They also eat a variety of foods, including dried food, live food, and frozen food. They are also peaceful tank mates and can live with other fish easily. In addition to this, these fish help clean up the tank by eating leftover food and other remnants that may gather on the sandy substrate, plants, and rocks.

Sterbai Cory breeding

Since these fish are hardy and tank safe, they can be captive-bred in a tank environment. For this, it is advised that for every female in the tank, there must be two males. When the females begin to look more rounded and large, it means that they are full of eggs and are ready to breed. When this happens, you must change the water to cooler water and increase the oxygenation in the tank. During the breeding season, males chase females around the tank until a suitor is chosen. Males and females release their sperms and eggs into the open water simultaneously, and fertilization takes place in the tank. Following this, the eggs settle at the bottom of the tank. Since these fish are bottom dwellers, they often look for food at the bottom of the tank. Hence, the adults must be removed from the tank so that they do not eat the eggs.
