Beginner Level: Pajama Cardinals
Cardinal fish tend to be a little underrated. Their peaceful nature and bold markings make these fish an excellent addition to a community saltwater tank. As carnivores, they will enjoy foods such as mysis shrimp, bloodworms, brine shrimp, pellets, and more. These fish like to school, so keeping them in groups of four, at the very least, will help ensure their happiness.
Make sure to provide these fish with plenty of hiding places, such as rocks and seagrass.
