Gertrudea Rainbow Fish, also known as the Spotted Blue-Eye. These peaceful nano fish are perfect for planted or community aquariums and thrive in small groups.

✨ Features:

  • Size: Grows up to 1.2 inches (3 cm)

  • Temperament: Peaceful, schooling species

  • Ideal for: Nano, community, and planted aquariums

  • Temperature: 75–82°F (24–28°C)

  • pH: 6.0–7.5

  • Diet: Micro pellets, baby brine shrimp, daphnia, crushed flakes

🌿 Behavior & Care:
Gertrudea Rainbows are active mid-to-top dwellers that shimmer beautifully under good lighting. Males display dazzling fins with white or yellow tips and often perform gentle courtship dances when females are nearby. Keep them in groups of 6 or more to bring out their best colors and natural behaviors.

💧 Tank Setup Tip:
They feel most at home in tanks with floating plants, driftwood, and gentle flow. Great tank mates include chili rasboras, pygmy corydoras, and shrimp.
