This species is best suited for a large, peaceful aquarium. A 30-gallon or larger aquarium with a cave and peaceful tank mates is suitable for this slow and methodical swimmer. As they prefer to hide in sea grass or use long spined urchins for camouflage, the aquarium should be decorated accordingly. If a larger aquarium is available, it will handle a small group of this species, which will establish a strict hierarchy without aggressiveness. It is important to ensure the aquarium is well-maintained to ensure the optimal health of the fish. Additionally, regular water changes are necessary to ensure proper water quality.

The Redtail Cardinalfish is a unique and hardy species requiring a well-balanced diet for optimal health. This includes a variety of meaty foods such as frozen brine or mysis shrimp, flake foods, pellet foods, and bloodworms. Maintaining a healthy diet for this species is essential for its longevity and well-being. Additionally, providing a variety of food options will ensure the Redtail Cardinalfish is receiving the nourishment it needs to thrive. Furthermore, regular water changes can help to ensure that the tank water quality is suitable for the fish.
