The Allen's Damsel is a vibrant and eye-catching fish, known for its electric blue body and yellow belly, with a slightly white tail. These fish grow to a maximum size of about 2 inches and are best suited for aquariums that are at least 29 gallons. While they are semi-aggressive, they generally coexist peacefully with other fish, corals, and invertebrates, making them a great choice for reef tanks. The **Allen's Damsel** adds a splash of color to any aquarium.

In smaller tanks, **Allen's Damselfish** may show aggression towards other damsels. To keep multiple **Allen's Damsels** together, ensure the tank is spacious. They thrive in environments with plenty of live rock for hiding. Avoid housing them with larger, aggressive fish. As omnivores, they require a diet rich in both meaty and plant-based foods. Feeding them mysis and brine shrimp, high-quality frozen foods, and premium flake and pellet foods will keep them healthy and content.
