Glowlight Rasboras are small fish, reaching a maximum size of 1.5 inches, making them perfect for nano and mid-sized aquariums. A minimum tank size of 10 gallons is suitable, but larger tanks (20+ gallons) are recommended for bigger schools. They thrive in densely planted setups with driftwood, leaf litter, and dim lighting, which mimic their natural blackwater habitat.

Care and Water Parameters
This species prefers warm, soft, and slightly acidic water, with:
Temperature: 73-82°F
pH Range: 5.5-7.0
Water Hardness: Soft to moderately hard
They are highly sensitive to water conditions, so regular water changes and good filtration are crucial for their well-being. Adding Indian almond leaves or driftwood can help replicate their natural tannin-rich environment.
‎
Diet and Feeding
Glowlight Rasboras are micro-predators that require a varied diet of small, high-quality foods to maintain their vibrant coloration. Their diet should include:
High-quality micro pellets and fine flakes
Live or frozen foods such as daphnia, baby brine shrimp, and microworms
Occasional vegetable-based foods like spirulina flakes for added nutrition
‎
Unique Behaviors
These peaceful, social fish do best in schools of at least 6-8 individuals, as they feel more secure and display better colors in larger groups. They are active swimmers, often seen darting through plants and engaging in synchronized schooling behavior. Their gentle temperament makes them excellent companions for other small, non-aggressive fish like tetras, rasboras, and dwarf gouramis.
