The Threespot Domino Damsel is a bold and hardy saltwater fish, named for the three white spots on its dark black body—one on the forehead and one on each side. It’s known for its energetic swimming and strong personality, making it a standout in fish-only or mixed reef systems.

• Grows to 2–3 inches

• Minimum tank size: 30 gallons

• Semi-aggressive – may become territorial, especially as it matures

• Reef compatible – safe with corals and most invertebrates

• Omnivore – eats flakes, pellets, and frozen foods

• Very hardy – tolerates a range of water conditions

• Can be kept singly or in groups (introduce together to reduce aggression)

A great choice for beginner saltwater aquarists who want a durable, eye-catching fish. The Threespot Domino Damsel brings contrast and attitude to any marine setup.
