Galaxy Rasbora Danio

Galaxy Rasbora Danio Margaritatus 

The Galaxy Rasbora, also known as Celestial Pearl Danio, is a small and captivating freshwater fish cherished for its vibrant colors and peaceful demeanor. Originating from Southeast Asia, it's a gem in planted aquariums due to its striking appearance and peaceful nature.

Origin: Native to the streams and ponds of Myanmar (Burma), these fish thrive in well-maintained aquariums resembling their natural habitats with ample vegetation and moderate water flow. 

Feeding: They are omnivorous and readily accept high-quality flake foods, micro pellets, freeze-dried or live foods like brine shrimp, bloodworms, and small insects. A balanced diet enhances their coloration and overall health. 

Tank Mates: Known for their peaceful temperament, Galaxy Rasboras coexist harmoniously with other small, non-aggressive species like other rasboras, small tetras, peaceful shrimp (like cherry shrimp), and small, peaceful bottom-dwellers like Corydoras catfish. 

Aggression: These Rasboras are exceptionally peaceful and do not exhibit aggressive behavior, making them an excellent addition to community tanks. 

Experience Level: Suitable for aquarists of various experience levels, from beginners to seasoned hobbyists. They thrive in well-maintained tanks with stable water parameters and appropriate tank mates. 

Water Parameters: Prefer slightly acidic to neutral water with a pH range of 6.5 to 7.5, Temperature :  72-78°F (22-26°C), and relatively soft to moderately hard water.

Regular water changes and a well-established tank are essential for their health.

The setup itself should mimic their natural habitat as closely as possible. Here’s what works best in my experience:

Water Parameters:

• Temperature: 72-78°F (23-26°C)
• pH: 6.5-7.5
• Hardness: 2-10 dGH
• Ammonia/Nitrite: 0 ppm
• Nitrate: Below 20 ppm

Tank Features:

1. Dense planting (especially with fine-leaved plants like moss, Rotala, or Cabomba)
2. Dark substrate to enhance their colors
3. Floating plants to diffuse lighting
4. Open swimming areas in the middle
5. Minimal to moderate flow

I always use sponge filters or gentle hang-on-back filters because strong currents stress these fish out. Lighting should be moderate, not too bright. The more comfortable they feel with hiding spots and plant cover, the more confident and colorful they’ll become. It’s counterintuitive, but providing more hiding places actually makes them more visible and active.
