Male Koi Galaxy

The Koi Galaxy Betta (Betta splendens) is one of the most striking and sought-after Betta varieties available in the aquarium hobby. Combining the bold marbled patterns of Koi Bettas with shimmering metallic “galaxy” spotting, each fish develops a unique appearance that makes it a true centrepiece specimen.

No two Koi Galaxy Bettas are exactly alike. Their vibrant mix of reds, oranges, blues, whites and metallic scales creates an ever-changing display of colour that can transform any aquarium into a living work of art.

Bettas are intelligent fish with plenty of personality and quickly learn to recognise their owners. Their graceful finnage, curious behaviour and stunning colours have made them one of the most popular aquarium fish worldwide.
