More than 50 species of nimble and motley members of the Melanoteny family in recent years have become very popular inhabitants of the aquarium. Perhaps the most popular representative of this interesting family is a resident of New Zealand red glossaryepis, which was first described in the distant 1908 of the last century.
The first attempts to import red glossas to Europe began in 1973. A few years later a group of fish was brought to Moscow from Tokyo.
Glossolepis are famous for their peaceful nature and livability with other peaceful neighbors.
The body of the fish is high, the ventral and dorsal fins are pronounced and at moments of play become very showy. The color of the body in red glossolepis is quite variable. In nature, there are individuals with a yellow-pink, burgundy and scarlet color.
In addition, the body has a silver-black inserts. Color variation is largely determined by feeding, housing conditions and the age of the fish itself.
As an example, you can consider feeding a pipe worker, thanks to which the color of your gloss-seps will be brick-gray. The color of the females is much more modest, on either side there is a golden or silver tint with a slight green tint.
The maximum body length of males does not exceed 15 centimeters, females – 10 cm.
G. incises like stable hydrochemical parameters of water, bright lighting and a large amount of aquatic vegetation. In addition, in the aquarium it is necessary to organize a powerful filtering, as the fish love clean water.
With frequent water changes and the first signs of bacterial dregs in fish, the body color becomes dull, they start to behave in isolation and practically do not take food.
In aquarium conditions, red glossrosepis can live up to 6 years with quality care. Because of their violent temper and high activity, the males of glossolepis can easily interbreed with various types of melanotenias.
A distinctive feature of all hybrids – a larger scale and the lack of gloss on the sides.
The fish reach sexual maturity at the age of one and a half years, and the males of the red gloss-soleps quite noticeably lag behind in the development of the females by about a quarter. Spawning can proceed both in pairs and in a pack.
A pair of fish requires a 20-liter aquarium with dimensions of 40 × 20×20 cm. However, the most spectacular spawning can be achieved if the producers are planted to spawn in a large 100-liter aquarium.
In such a tank, the competing males will swim excitedly around the females and will in every way reflect the attempts of various violators to enter the occupied territory. As a substrate for spawning, you can use the roots of floating plants, such as pisti or eichornia, Javanese moss, Riccia.
If you kept your producers separately before spawning and strongly fed with live food and zooplankton, then salvo spawning is possible. If the spawning takes place in the general aquarium, the female can lay eggs every day for a couple of weeks in small portions.
The maximum fecundity of females over the entire spawning cycle can reach 700–900 eggs.
The incubation period for caviar can be delayed up to 10 days, and the hatching itself is uneven and can last for about two weeks. Starter feed for the larvae are rotifers, egg yolk, Artemia nauplii. Cyclops larvae, which in warm water turn into adult predators, carry some danger for weak fry.
Glossolepis grow extremely slowly and within a month reach a length of 1 centimeter. As a preventive measure, it is necessary to add methylene blue in a ratio of 0.5 mg per liter of water and table salt to aquarium water with fry.
