The **Ruby Cardinal** is a breathtaking fish, showcasing a vibrant red hue. These fish have a rich red body that is entirely red.
**Ruby Cardinals** grow to a maximum of about 2 inches and can thrive in aquariums as small as 29 gallons. They are generally peaceful and won't disturb other fish, corals, or invertebrates, making them ideal for reef aquariums. However, they can be territorial with other cardinals and should be kept in small groups. Avoid housing them with larger, aggressive fish, as they are not well-equipped to defend themselves. Providing ample live rock will offer them necessary hiding spots.
Uniquely, **Ruby Cardinals** are nocturnal, adding lively movement to your tank during nighttime hours when most fish are resting.
As carnivores, **Ruby Cardinals** need a diet rich in meaty foods. Feeding them mysis and brine shrimp, high-quality frozen foods, and premium flake and pellet foods will ensure their health and happiness.
