Minor fish (Hyphessobrycon minor) is a freshwater fish of the Charac family
Minor aquarium fish mixed with serpas (Hyphessobrycon eques) from which they almost do not differ. Serpasas live in nature in the west of Brazil, in Bolivia and Paraguay.
Fish in minor in nature – schooling. Keeping alone is aggressive or hiding in shelters. Depending on the size and nature of the neighbors.
A school of 6–8 individuals has little interest in other fish.
The body is elliptical, elongated, laterally compressed. In an aquarium, the minor fish grows up to 4–4.5 cm. The color varies from yellow with a greenish tint to an orange-red.
The dark spot behind the gill covers indicates proximity to the serpas.
Fins are red with dark–gray or black edge, except tail. The color of the dorsal fin varies from gray-black to orange-red with a dark border, the characteristic shape is trapezoid.
Anal – extended to the base of the tail. Caudal fin – forked.
Minor fishes swim mainly in the lower and middle layers of the can. Active, continuously in motion, playful.
Inside the beak there are conflicts between males for supremacy, but they do not reach injuries. They love shelters.
The average is 3-4 years. In recommended conditions – up to 6 years.
A common mistake is the institution of a couple of minors. It is impossible to determine the sex of acquired young fish. Males without females are at enmity, attack neighbors.
The best qualities of fish show if there is in the bank from 5-6 tails. The composition of water and temperature conditions are important when diluted.
Desirable filtering and aeration with the creation of sluggish flow.

For a flock of 5–8 individuals, a bank of 60 liters is suitable. The width of the vessel should not be less than 0.7 m. The optimal shape is a rectangular parallelepiped.
Angular and cubic tanks will not provide space for swimming.
In the center of the banks provide a place for swimming. Plants and decorative elements are located at the rear and side walls.
- Medium temperature: 24–27 ° C. Below 20 ° C, minors get cold and lose their immunity.
- Acidity: neutral or acidified, pH 6–7.5.
- Stiffness: medium hardness, 1.5–8 ° Ж.
Weekly replace 1 / 4–1 / 3 of water with settled water for 24 hours.
Designers do not recommend placing purchased plastic “palaces” in an aquarium. In imitating natural conditions look ridiculous.
The abundance in the counterfeit market forces one to fear for the chemical safety of such products.
Scenery cover should not have sharp catch and fragments. Active and fast minors are scratched and become infected with fungal infections.
Green thickets will serve as shelters for fish and support biological balance. Anubiases, Javanese moss, elodey will do.
On the surface – salvinia.
Rolled pebbles 4-6 mm.
When there is insufficient light, the Minor fish lose their color intensity. They look at a light flux of 50–70 lumens per liter of vessel.
Focus on fluorescent and LED light sources. LED choose with a color temperature of 8000 K. The length of daylight hours is 10–12 hours.
Preferred live (bloodworm, tubule, Grindal worm, fruit flies) or frozen feed. Dry do not contain the necessary substances in the right amounts, swell in the stomach.
Be careful with the amount of food. Fish do not feel satiety, maybe obesity. Feed once a day.
Arrange 1-2 days a week – unloading.
20–25% of the diet is plant food. Feed vegetables: cucumber, blanched cabbage, zucchini.
Minors are compatible with peaceful fish of comparable size (petsilievye, except guppies, neons, danios). A depressing effect on sluggish species, bullied. They will constantly jerk their fins while they are preparing for defense.
Fins irrespective of the size of the individual (cockerel, angelfish, guppy). There have been cases of attacks on shrimp and snails.
It will take a shaded spawning with weak aeration. Suitable “trough” for 12-15 liters.
Water layer – up to 15 cm.
Cook the peat broth. Per 100 g of broth add 4-6 g of peat. Peat use clean, without mineral additives: dangerous for fish.
Cook for 25–30 minutes on low heat. After cooling, filter the precipitate.
Add to spawn until the water is slightly brown. Environment settings:
- temperature: 26–28 ° C;
- hardness: up to 4 ° W;
- acidity: pH 6–6.5.
To protect the eggs from eating, use a separator or mark them on the bottom of the plant (Javanese moss, hornolistnik). Or land ground cover plants.
Dimorphism appears after puberty. The dorsal fin of the male is elongated, the color of the female is paler. When viewed from above, the male looks fry, the female has a belly.
Males are easy to distinguish by behavior: tend to dominate.
The inner difference is the shape of the swim bladder. It can be seen in the light.
The male elongated with a point, the female – oval.
In the second half of the day, the female with the “belly” and the male will spawn in the spawn. The label starts at night and ends in the morning. Caviar sinks, does not stick to the equipment and plants.
At the end of a couple otsadite. Minors usually bring 250–300 eggs.
Larvae appear every other day. On the fifth day they begin to swim and search for food.
Connect the filtering.
Starter feed – nauplii, daphnia. Divorced at home.
Faded boiled yolk of chicken egg. Plant food – zooplankton. Put a jar of water in a warm place in the sunlight.
When the water blooms, take a water syringe with algae with a medical syringe and pour over the little minors. Feed plenty 5-6 times a day.
Fry grow intensively and do not suffer from obesity.
Replace 1/4–1/3 of the volume weekly. Watch for dirt buildup on the bottom, siphon.
After a couple of months, reduce the number of daily feedings to 3. Diversify the diet with dry food, chopped oatmeal (“Hercules”). Add chopped bloodworm, tubule. Adults are considered to be fish after puberty at the age of one.
Switch to adult feeding mode.
Aquarists are captivated by the exterior and the cheerful behavior of the minors. Note omnivorous and unpretentiousness to food, environmental parameters, low cost in pet stores.
Disliked veiled fins fins and mandatory content with a flock. Confused difficulty breeding.
Sold for 80–120₽, depending on age and exterior. Veiltail species are more expensive.
