Blue Eye Gertrudae Rainbow (Pseudomugil gertrudae)

Blue Eye Gertrudae Rainbows, more accurately known as Gertrude’s Spotted Blue-eyes, are a small and highly attractive rainbowfish relative known for their bright blue eyes, fine yellow coloration, and beautifully spotted finnage. They are an excellent choice for peaceful nano and planted aquariums, especially for hobbyists who enjoy active, delicate-looking fish with constant movement and display behavior. This is a small species, with adults generally staying around 30 mm standard length, making them much better suited to smaller peaceful aquariums than larger rainbowfish species.

• Constant movement and active mid-to-upper water behavior
• Excellent choice for peaceful planted aquariums
• Small adult size makes them great for nano-style community setups
• Males display beautifully toward each other without the heavy aggression of larger fish.
