Galaxy Microrasbora (Danio margaritatus) is one of the most stunning and sought-after miniature fish in the aquarium hobby. With its deep blue-black body adorned with pearlescent spots and striking bright red fins, this tiny fish looks like a living jewel in any planted tank.
Growing to a maximum size of just 2-2.5 cm (about 1 inch), these peaceful schooling fish are perfect for nano aquascapes, heavily planted tanks, and peaceful community tanks with dwarf shrimp. To display their best coloration and reduce shyness, they should be kept in schools of at least 8 to 10 individuals.
