Original description: N. Annandale 1918. Fish and Fisheries of Inle Lake. Rec. of Ind . Mus 14; 33 to 78.

 

Type specimen: Microrasbora erythromicron

 

Type locality: Inle Lake

 

Distribution: Inle Lake and Kaya State

 

Habitat: The little fish of this species are abundantly found only at the edge of the Inle Lake, among the stems of decaying grass of floating island.

 

Characters: Body is short and strongly compressed. Mouth is small and oblique. The scales are very large The color of live specimen has deeply suffused with scarlet, with bluish vertical stripes on the body. A black spot is on the caudal peduncle. Fins are hyaline..             

 

Sex differences: The male has broad vertical blue bands on the side of the body, female has thin blue bands.

 

Aquarium keeping: The fish is suitable for community tank. Thick aquatic plantation favors the fish to enrich the beautiful color.  The pH should be slightly higher than 7, dH 10o to 20o, and the temperature range 20o to 25o C.

 

Spawning:  The tank size for breeding is 30 x 20 x 20 cm. The water quality should be slightly hard and alkaline (pH slightly greater than 7, dH 10o to 20o). The tank should be well planted with java moss as the spawning media. Danio erythromicron is continuous spawner and their eggs stick to the media. The better way to breed the fish is to separate the moss with eggs to other hatching tank (For 10 liter, the size is 30 x 20 x20 cm) with the same quality of water as in the breeding tank. They will hatch after 3 days of spawning and free swimming of fry can be observed after 7 days of hatching. Infusoria, rotifer (if available) are good for primary food. After 7 days or 10 days of feeding either infusoria or rotifer, newly hatched brine shrimp should be ready to feed.
