Corydoras polystictus is a small tropical fish that lives in freshwater.
This fish is part of the Corydoradinae subfamily within the Callichthyidae family.
It comes from South America, specifically the Paraguay River area in Brazil. This fish eats worms, small water creatures, insects, and plants.
It lays its eggs in thick plants, but the parent fish don’t protect the eggs.
There’s another fish called Astyanax bimaculatus that follows the Corydoras polystictus around.
This is because the catfish stirs up food like insects, small water creatures, plant bits, and algae while it’s searching for its own food, making it easier for the Astyanax bimaculatus to eat as well.
