With its striking colors and peaceful demeanor, the Galaxy Rasbora is a favorite among aquarists who appreciate small schooling fish with vibrant personalities. Let's delve into the notable features, care requirements, and considerations for keeping Microrasbora erythromicron in your tank:

Appearance:

• Colorful Beauty: The Galaxy Rasbora is known for its sparkling iridescent body, with a deep blue or green hue and contrasting orange-red markings.
• Micro Size: This tiny species reaches a maximum size of about 1 inch (2.5 cm), making it suitable for smaller tanks.

Behavior:

• Peaceful Shoaling: Galaxy Rasboras are social and prefer to be kept in groups of at least six individuals, where they display natural schooling behavior.
• Compatibility: They are peaceful and can coexist with other small, non-aggressive fish species.

Tank Setup:

• Tank Size: A nano tank of around 10 to 20 gallons (38 to 75 liters) is appropriate for a small school of Galaxy Rasboras.
• Aquascape: Create a natural environment with live plants, driftwood, and fine-grained substrate. Use dim lighting to mimic their natural habitat.
