Galaxy Rasboras (also known as Celestial Pearl Danios or Danio margaritatus) are stunning micro-fish prized for their starry pattern that resembles a miniature night sky.
Appearance: Features a deep blue-to-grey body covered in pearl-like gold spots, with bright red and black striped fins.
 Size: Very small, growing to only 0.75–1 inch (2–2.5 cm).
 Behavior: Shy, peaceful shoaling fish that feel safest in groups of 6–10 or more; males occasionally display harmless "dancing" spats over territory.
 Care: Ideal for nano tanks; thrives in clean, well-planted aquariums with cool-to-warm water (70–78°F / 21–26°C), gentle flow, and small foods like micro-pellets or baby brine shrimp.
