The fish will reach 1.8 in (4.5 cm) in length (4.5 cm).
Physical Characteristics and Behavior
A Corydoras atropersonatus can grow up to 1.8 inches in length. They can appear to blink because of the way their eyes can slant, which they can do. These fish have the freedom to swim to the surface whenever they feel the need because their highly vascularized intestines enable them to take oxygen from the air. Because of the fact that these animals can breathe air from their surroundings, the aquarium needs to be covered and the water level needs to be kept low.
Keeping and Care as a Pet
- Water Conditions
Water with a pH of 6.0 to 8.0 and a temperature of 70 to 75 degrees Fahrenheit are ideal for keeping this species in captivity.
- Tank Setup
Incorporate hiding spots, plants, and sand into the tank. It is ideal to take care of these fish in a communal setting, such a community aquarium.
- Tank Mates
Very calm neighbourhood fish. They won’t purposely bother the fish in the aquarium, but their fumbling around the tank could annoy more delicate fish or other bottom dwellers. It’s better to keep them in groups of 5 or more.
- Diet
These fish will consume the majority of food that sinks to the bottom of the tank, as is true with most Corydoras. Flake food or other sinking meals, such as catfish pellets, should be added to sinking algae pellets as a supplement.
You should be aware that these fish have a carnivorous side and enjoy eating things like bloodworm and brine shrimp. Foods made of vegetables don’t provide much nutrients for them. Injured, dead, or even dying fish that remain on the substrate for an extended period of time will also be eaten. They are quite opportunistic!
