Celestial Pearl Danio

The Celestial Pearl Danio or Galaxy Rasbora, (Danio margaritatus) is one small but beautiful freshwater fish that is sought after for its stunning colors. The blue-black colored body with white spots resembling pearls appearing as stars, where the bright orange or red fins provide even greater dramatic contrast. Males should be best colored with reddish fins, whereas females are bloated and drab.

Ever since its discovery in 2006, the fish has been a favorite among aquarium hobbyists due to its warm nature, small size, and reasonable level of community tank tolerance. In spite of its dainty look, the fish is very hardy under favorable conditions, thereby deserving its recognition even to new owners.

Origin of the Celestial Pearl Danio

Celestial Pearl Danios live in shallow, vegetation-filled fresh water lakes and ponds of Myanmar. The environments are peaceful, heavily vegetated, and shallow with abundant food and shelter for the small fish. Their relatively restricted natural range caused early overcollection concern but are nowadays extensively cultured in aquaria and may be obtained without threatening wild populations.

Temperament of the Celestial Pearl Danio

Celestial Pearl Danios are peaceful, schooling fish and like to be in schools. Males will show fleeting moments of aggression during spawning or territorial disputes but never become aggressive and even make good viewing. Due to how peaceful they are, they are suited to planted tanks as well as community tanks with tank dwellers of similar size.

Celestial Pearl Danio Compatibility with Other Fish

Celestial Pearl Danios coexist well with most other small, peaceful fish species. The following are suitable tankmates:

1. Neon tetras, ember tetras, and harlequin rasboras
2. Corydoras catfish
3. Small snails and shrimp
4. Other peaceful danios or microfish

Do not keep them with territorial, large cichlids or barbs as they will fin nip or regard danios as food. Keeping them in groups of six or more members prevents stressing and displays natural shoaling behavior.

Price Range of Celestial Pearl Danio

Celestial Pearl Danios are rather expensive for their fame. They retail between ₹150 to ₹400 (US $2–5) per fish. Due to their small size, aquarists do buy sets, which is more expensive but guarantees proper schooling behavior.
