These bottom-dwellers are peaceful fish and relatively easy to care for, often hiding during the day but coming out to feed during dusk or dawn. They prefer being in shoals of at least three individuals but can thrive with larger groups of up to 8 – 10.
In addition, these fish benefit from having plenty of hiding places to feel safe throughout their environment, such as clay flower pots, driftwood pieces, or plants like Java Ferns or other low-light plants.
The Panda Corys are omnivorous feeders and will accept most sinking foods, including small flakes and pellets explicitly formulated for Corys, frozen foods like brine shrimp and bloodworms, and live food options like micro worms or daphnia.
It’s important that these fish remain well-fed since underfed specimens may become bullish towards others in its school; therefore, regular feeding intervals should be established to maintain proper health amongst all tankmates, including any invertebrates present within the aquarium parameters.
