Sinorhodeus Microlepis

Sinorhodeus Microlepis, also known in the aquarium world as the Red Rainbowfish (Glossolepis incisus), brings a living splash of color and activity to tropical freshwater setups. Its striking red body and shimmering fins catch the eye from every angle, turning a simple tank into a lively focal point that's as dynamic as it is beautiful.

What makes this fish stand out

• Vibrant color and graceful presence: a bold red body paired with iridescent fins that flash as it glides through the water, adding depth and motion to planted or open-tank layouts.
• Peaceful, sociable schooling fish: thrives in groups of 6 or more, turning schooling behavior into a visual spectacle while staying compatible with other calm, peaceful community species.
• Adaptive for planted and open tanks: enjoys well-planted setups with gentle to moderate currents, with colors that pop under both natural and LED lighting.
• Relatively easy to care for: suitable for intermediate hobbyists and confident beginners when provided with stable tropical conditions.
• Long-term enjoyment: with proper tank maintenance, lighting, and diet, can thrive for several years, rewarding you with consistent color and activity.

Care and setup for optimal color and health

Create a stable tropical freshwater environment to showcase the Red Rainbowfish’s best attributes. Keep the water warm and clean, with a pH close to neutral and a temperature range roughly around 75–82°F (24–28°C). A well-filtered tank with a gentle current helps mimic its natural habitat and reduces stress, which in turn sustains color intensity and active schooling behavior. For housing, start with at least a 20-gallon tank when keeping a small group of Glossolepis incisus, and consider 29 gallons or larger as your school grows. Submerged plants, driftwood, and secure plants provide retreat spots and grazing surfaces, while open swimming lanes keep the fish’s energy and color on display.

Diet and feeding tips

The Red Rainbowfish is an adaptable omnivore that benefits from a varied diet. Offer high-quality flakes or micro-pellets as a staple, supplemented with small live or frozen foods such as daphnia, brine shrimp, and finely chopped shrimp. Feeding in small, frequent portions helps maintain water quality and encourages natural foraging behavior, enhancing color expression and vitality.

Ideal tank mates and community setup

This species shines in a community tank with other calm, non-aggressive fish that share similar water parameters. Suitable tank mates include peaceful tetras, small rasboras, and dwarf gouramis. Avoid aggressive competitors or species that nip fins, as the Red Rainbowfish’s beauty is best enjoyed in a relaxed, harmonious environment.

Lighting and display tips

Lighting plays a key role in bringing out the full spectrum of color in Glossolepis incisus. Use a balanced lighting setup that highlights the red body without washing out the fins.
