Glossolepis red (Glossolepis incisus) – content, breeding

Glossolepis incisus Glossolepis red Weber, 1908.

Glossolepis red – a bright fish of rich red color was discovered in 1908, but it only appeared in domestic aquarists in the late 70s.

They call it differently: Aterina Red, New Guinean Iris, Red Iris, Comb Iris.

Habitat: Indonesia is endemic to Lake Sentani and its tributaries in the north of New Guinea. Usually found in shallow waters with rich vegetation.

The lake is connected to the ocean by a small channel and contains an interesting combination of species.

The natural habitats of Glossolepis red are: Lake Sentani and one of the tributaries of the river Jaipuri.

Description: body shape elongated, flattened at the sides. The males have a sharply arched back line. For fish, as for all iris, is characterized by thick lips and large eyes.

Forked tail. The dorsal fin is formed by a short front part and an elongated second part displaced to the tail.

Anal fin is long.

Glossolepis males are distinguished by a deep red color with a silver luster, the brightness of which depends on the conditions of detention. On the sides they have transverse stripes burgundy color.

Females look not so impressive and are painted in greenish or yellowish color, rolling on the back in olive. On a body small thin cross strips are chaotically scattered. Males have fins red, females are transparent.

Fish differ in the color of the iris of the eyes, which is golden in females and red in males.

Under natural conditions, males of red atherine grow to 15 cm, but in aquariums much less – up to 10 cm.

Glossolepis male and female

The size of the females does not exceed 7-8 cm.

Arrangement and parameters of the aquarium: schooling fish and ideally need to contain from 6-8 individuals, preferably more with an equal number of males and females. For such a number of Salsolepis you need an aquarium of at least 100, and preferably 200-300 liters, and always with a lid, as the fish are prone to jumping when they are frightened. Plants do not damage, and there are no restrictions on their choice, but it is desirable that these be species with a saturated green leaf color – then the color of the iris only wins.

Planted vegetation need around the perimeter, leaving free space for swimming.

From the scenery fit stones and decorative grottoes. The main thing is not to overload the reservoir with them – comb iris (Glossolepis incisus) a spectacular fish in itself and an excess of scenery will be distracting.

Water parameters: 24-27 ° C, withstand fluctuations in the range of 22-30 ° C, pH 7.0-8.0, dH 10-20.

Filtration with aeration required. Water movement should be fairly gentle.

Frequent replacement of a quarter of water will positively affect the beauty of atherin.

They have a peace-loving nature, but can disturb smaller or slow-moving fish with their fast movements and relatively large size. Ideal neighbors will be others with similar sizes of iris, danios, barbs, somas, such as Corydoras.

Nutrition: are omnivorous, but they are particularly weak for protein-containing feeds, such as artemia, bloodworms, pieces of beef, cyclop, daphnia, strawberry and shrimp. Sometimes you can treat fish with ants.

The diet strongly affects the brightness of the color, so live food should be alternated with dry and vegetable, as well as adding food with carotene.

Reproduction: able to spawn in general and in a separate aquarium. The second option is preferable.

Small-leaved plants, for example, Javanese moss, which will serve as a substrate, are placed in a spawning tank of 70 liters of elongated shape. You can replace it with a nylon sponge.

Soil is not needed, but it is obligatory to install a filter (possibly an air filter) to enrich the water with oxygen and create a small flow.

Water parameters in spawning: 23-26 ° C, pH 7.5, dH 18-25.

A pair or two females and four males are pre-deposited in separate tanks for 1-2 weeks. During this period, producers should eat plentifully and varied.

A slight increase in temperature may cause spawning.

Usually red iris spawns for several days, but sometimes the process stretches over several weeks. Every day, the female throws out several transparent and sticky eggs about 1 mm in size, which first float freely in the water, and then fixed to the substrate.

The performance of the female is a maximum of 700 eggs.

To prevent the parents from eating the eggs, they should be fed very abundantly, but it is better to periodically move the eggs to a separate container with water from the spawning aquarium, and add new moss to the spawn.

Incubation of caviar lasts about 7-8 days. The hatched fry first float to the surface for a breath of air, and then immediately need food. Juveniles receive live dust, cyclop nauplii, ciliates and rotifers.

After a week or so, they start taking Artemia nauplii. Fry grow very slowly and in the initial stages are especially sensitive to water quality.

Sexual maturity reaches 1-1.5 years.

Glossolepis incisus Glossolepis red lives 5-8 years.

Interestingly, when the glossosepicus is at a temperature just below the optimum, all males turn red, while in warmer water only the dominant males will be painted red.
