The Philippine Blue Angelfish is a breathtaking genetic marvel. Its base body color can range from silver to platinum, but what makes it truly special is the presence of the “Philippine Blue” (pb) gene. This gene creates a structural color, meaning it’s not a pigment but rather the way light reflects off the scales, producing an incredible, shimmering blue. The intensity of the blue can vary depending on the fish’s mood, health, lighting, and genetic makeup (fish with two copies of the blue gene, often called “Pinoy,” display a deeper, more solid blue).
Like all angelfish, the Philippine Blue is a cichlid and possesses a classic cichlid personality. They are generally peaceful but can become territorial with their own kind and may bully smaller, more timid fish. They are known to prey on very small fish (like nano rasboras or newborn shrimp).
To truly thrive, a Philippine Blue Angelfish needs a suitable environment that caters to its unique body shape.
Bring a flash of electric blue to your aquarium with the Philippine Blue Angelfish. Its elegant form and mesmerizing color make it a stunning centerpiece for any dedicated aquarist.
Perform weekly water changes of 20–30% to keep water quality high and colors vibrant.
Feed a mix of high-quality flakes or pellets as the staple diet, supplemented with frozen or live foods such as brine shrimp and bloodworms. Occasional blanched spinach or peas can help digestion. A varied diet enhances coloration, especially the signature blue sheen.
Philippine Blue Angelfish form monogamous pairs and spawn on flat surfaces such as leaves or aquarium glass. Condition breeding pairs with protein-rich live foods. Once eggs are laid, some pairs guard them diligently, while others may eat them if stressed — consider removing eggs to a separate hatching tank.

Use good lighting, maintain excellent water quality, and feed a varied diet with high-quality proteins and occasional frozen or live foods.
Not strictly, but live plants help mimic their natural environment, reduce stress, and encourage natural behavior.
They can be bred at home with stable water conditions and flat spawning surfaces. If parents eat eggs, hatch them in a separate tank.
