Emerald microassembly (Microrasbora erythromicron) ANNANDALE, 1918.
The emerald microassembly is a shy but very beautiful fish that is not very common among aquarists.
Most suitable for content in nano-aquariums.
Also called Danio Erythromycron, Microselect Tape, Rasbor Erythromicron.
Habitat: The emerald micro-dwelling lives in shallow, dense vegetation of Myanmar lakes.
Description: The body of the tape micro-assembly is elongated, dense and colored mainly in a pinkish-orange color, the abdomen is lighter and the back is brownish. Vertical stripes of emerald color are located throughout the body, which can be up to 15 pieces.
At the base of the caudal fin there is a dark spot in the golden edging. Gill covers reddish.
The zebrafish erythromycron females are fuller and larger than the males, their fins are transparent, and the males are red-orange, as is the throat.
A miniature fish grows no more than 3 cm.
Arrangement and parameters of the aquarium: dwarf pack – a schooling fish, therefore, it is desirable to keep it in the amount of not less than 10 individuals, for which a capacity of 20-30 liters will be enough.
The presence of densely planted plants is necessary, since the emerald micro-collection is a very shy fish. At the same time there should be free swimming areas, which, moreover, will allow to observe the danios.
Snags will also be appropriate.
Against the background of a dark background and soil (necessarily small), erythromicron look much brighter.
Too bright light scares the fish, so to mute it, you need to put floating plants in the aquarium.
Filtering should be smooth, imitating the environment that is natural for micro-fusions. Aeration and a 30% weekly water change are also necessary.
Water parameters: 22-28 ° С, optimal 23-26 ° С, pH 6.5-7.7, dGH 5-18 °.
As neighbors for dwarf rasboru (Microrasbora erythromicron) only the same tiny and peaceful species will do. In addition, danios become more confident in the presence of fish of similar size and living in the middle water layers and near the surface.
The best neighbors will be Espei (Trigonostigma espei), Amanda’s tetra (Hyphessobrycon amandae), miniature haratsinovye and rainbow fish.
When kept with large and aggressive species, the emerald micro-collection will be constantly hiding.
It is possible to keep with shrimps, but only with adults, since babies can be eaten by danios.
Nutrition: The ribbon rasbor has a very small mouth, therefore, the feed should be small: cyclops, artemia, daphnia, tubule, carreter. Dry and frozen foods can also be used if they are chopped.
The presence of Artemia and Cyclops in the ration enhances the coloring of the zebrafish and prepares for spawning.
Reproduction: under comfortable conditions, an emerald micro-collection can spawn in the general aquarium. Eriromicrons spawn continuously, but given that parents are not against eating their caviar, a very small number of fry usually survive.
To obtain fry in sufficient quantities, a spawn of 10–20 liters is required, in which several pairs are placed (Microrasbora erythromicron). For successful spawning, males and females are kept separately for several weeks, and the basis of nutrition during this period is live food.
Run spawning fish should be in the evening, first females, then males. Darkness helps them to settle down, and in the morning, as a rule, spawning begins.
The tiny amber caviar, no more than 1 mm in diameter, the female lays on the moss, which must be immediately removed so that the producers do not eat the caviar, and place a new one in return.
A week later, the adults settle in a common aquarium.
With a stable temperature of 25 ° C, the development of larvae lasts 3 days. You can begin to feed the fry when they learn to swim horizontally, without falling to the bottom.
Starter feed – “live dust”, ciliates, as well as specialized live and dry food intended for fry, then Cyclops and Artemia nauplii.
Fry that are 1 cm long can be transplanted into the general aquarium.
Providing the necessary conditions Emerald microassembly (Microrasbora erythromicron) lives up to 3 years.
