Blue Moscow Guppy
Deep metallic blue from body to flowing fins.
Blue Moscow guppies are prized for rich blue coverage that can shift from royal blue to teal as the fish turns. This guide explains their appearance, care, tank setup, and healthy selection.
What makes a Blue Moscow guppy different?
The Moscow name describes a line with strong body color rather than color limited to the tail. Good examples show blue across much of the body, dorsal fin, and caudal fin. Lighting, age, genetics, and background can change how dark or green-blue the fish appears.
Best aquarium setup
- Use a fully cycled freshwater aquarium.
- Provide gentle to moderate filtration.
- Add plants and open swimming room.
- Keep ammonia and nitrite at zero.
- Avoid aggressive or fin-nipping tank mates.
Choosing a healthy fish
Look for open fins, controlled swimming, clear eyes, a straight spine, and a strong feeding response. Choose health before the deepest blue color.
