Celestial Pearl Danio (Danio margaritatus) is the small spotted fish many aquarists still know as Galaxy Rasbora. It suits mature planted aquariums where a group can move through moss, stems and open pockets without being pushed around by larger fish.

Quick facts

Scientific name	Danio margaritatus
Adult size	2-2.5 cm
Minimum aquarium	45 litres or larger
Temperature	20-24 C
pH	6.5-7.5
Temperament	Peaceful but shy nano shoaler that needs plants and a group
Diet	Micro omnivore; fine flakes, micro pellets, small frozen foods, daphnia and baby brine shrimp

Care and setup

Use a planted aquarium with gentle flow, fine cover and stable water. The fish is peaceful but shy, so it shows best in a group of 8 or more with other small calm species.

Galaxy Rasbora remains a familiar hobby name, but the public care facts here are standardised to Danio margaritatus.

Feeding

Feed tiny foods: fine flakes, micro pellets, daphnia, cyclops and baby brine shrimp. They have small mouths, so crush larger foods and avoid fast tank mates that take everything first.
