Kaudern’s Cardinalfish Information

Cardinalfish are nocturnal in nature and spend the most time in cooler areas of the aquarium. They will be out at night. They’ll learn to adapt to the brighter, more lit aquarium as time passes. Cardinalfish are often seen in groups in the wild, but they can fight in groups within smaller aquariums. In other circumstances, they can be peacefully surrounded by other non-aggressive fish.

Kaudern’s Cardinalfish Diet

Feed small, meaty meals frozen or finely chopped cooked foods. Cardinals consume small fishes as well as mobile crustaceans found in the wild. If your Cardinalfish seems to be not eating, feed it when the aquarium lights go out. A majority of Cardinalfish exhibit nocturnal habits and would prefer feeding after the lights are turned off inside the aquarium.
