Origin[edit | edit source]

Asia: Myanmar

Sexing[edit | edit source]

Males have brighter colours and the male develops slightly dark markings on their barbels. Females have less intense colouration and virtually clear ventral and caudal fins.

Breeding[edit | edit source]

Early rumors that Danio Margaritatus is nearing extinction in the wild due to collection for the aquarium trade proved false. Nevertheless, the rumor persists and keeps prices high. This species is adaptable to captive breeding and tank raised specimens are sometimes available. Danio margaritatus are egglayers, utilising a breeding mop or vegetation (such as java moss). The adults will eat any eggs or fry they find. The eggs are only slightly adhesive so are not guaranteed to stick to the moss or breeding mop when removed to a fry tank.

Tank compatibility[edit | edit source]

Species tank only, mainly due to their size. Will happily thrive in a well planted small tank. Can be kept with similar sized fish such as Otocinclus, and the smaller Rasboras.

Diet[edit | edit source]

Mostly seem to prefer small live food such as daphnia and baby brine shrimp. Will also take small pellets or crumbled flakes.

Feeding regime[edit | edit source]

Feed once or twice a day.

Environment specifics[edit | edit source]

These fish do well in densely planted mature tanks.

Behaviour[edit | edit source]

Males can get in scuffles with each other, therefore keep in large enough mixed groups of male/females of 6 or more to spread this aggression.

Identification[edit | edit source]

Striking tiny fish, with dark blue flanks covered in tiny yellow spots. Their belly is lighter in colour and their fins are striped with orange and black bands.
