When the celestial pearl danio was first discovered it cause great excitement with its spectacular colour and pattern. For a time there were fears for its existence as so many were being caught for the aquarium trade that there was a danger of extinction in what was thought to be its only habitat in Myanmar.  Since then it has been discovered in more locations in Myanmar and in Thailand and has proved relatively easy to breed, with most stock available having been captive bred.

Compatibility

Celestichthys margaritatus is a shy, even timid species and shouldn’t be kept with much larger or more boisterous fish as it may fail to compete for food. Tank mates should be similarly sized species’ that share its water parameters and having tankmates that swim up at the surface can make it bolder. Don’t mix with Celestichthys erythromicron as they are very closely-related and may hybridise.

Housing and Feeding

This species prefers a heavily planted tank and floating plants to provide overhead cover are beneficial. Having plenty of plants will mean you see more of the fish as their confidence increases with the easily available cover to dart into if they feel the need. Filtration should be gentle.

The celestial pearl danio will take most foods offered, but food needs to be small as they have tiny mouths. Commercial foods such as micropellets and crushed flake can be used as staples, though I have found they prefer sinking foods over those that float or hang in the water column. Live baby brine shrimps and small daphnia are a great addition to their diet, as are small frozen foods and should be offered often.

Breeding

Celestichthys margaritatus is a typical egg-scatterer and takes no care of its own eggs. It will eat its eggs and any fry that hatch so you will need a separate breeding tank from which the adults can be removed after spawning to have any real success in breeding these.
