Minnow Fish – In recent years, wildlife has undergone significant changes under the influence of man. Because of this, the Minnow fish’s natural habitat has also changed dramatically.
At one time, this species was considered completely extinct, but then its population was discovered in China. Today, the Minnow fish is considered an extremely rare fish and is protected by the Chinese government program. All aquarium fish of this species are raised in captivity.

Minnow Fish Appearance
Minnow fish is small in size and has a very bright attractive color. The length of his body can reach 4 cm. Life expectancy, like all small fish, does not exceed one and a half years.
In natural conditions and artificial ponds, Minnow fishes prefer to swim in the upper layers of the water, extremely rarely descending into the bottom areas.
This fish has no antennae. The dorsal fin is located with the anal on one longitudinal axis. The body color is brownish-bronze, along the entire body from the tail to the head there is a bright fluorescent strip.
The golden minnow fish is distinguished by the body color corresponding to the name, which near the tail ends with a black dot. On the tail and fins, the fish may have a bright red spot, and the caudal fin is partially transparent.
The abdomen has a lighter color compared to the back. Fry is characterized by the presence of a blue stripe on its side, which disappears with age.
Minnow Fish Gender Difference
Males and females of the minnow species do not have obvious external differences, however, their sex can be determined by color, size and body shape:
- males are smaller;
- the color of females is less bright;
- the male’s body is oblong, and the female has a rounded belly.
At the age of 6-13 months, the fish reach puberty. From this time on, males begin to attract the taking out of females and “show off” to each other, exposing the brightest parts of their body and spreading their fins wide.
Minnow Fish Aquarium Living Conditions
To keep the Minnow fishes at home, it is better to use an elongated aquarium. It is not necessary to look for a large capacity; for a flock of 5-7 individuals, 15 liters may be enough.
However, ideally, you need to settle such a group in a spacious 40-liter aquarium. The height of the water level must be at least 20 cm.
The optimal conditions for keeping the minnow fish are as follows:
- Water temperature is preferred from 18 to 22 degrees. If the water is warmer, the minnows will begin to lose their bright color, and their life expectancy is reduced.
Sudden changes in water temperature are unacceptable – this leads to a decrease in minnows resistance, and they become ill with fungal infections.
- Water hardness is preferred from 4 to 20 °, the reaction of the medium is 6.5-7.5.
- It is very important to provide aeration and a good filter. Once every 7-10 days, water must be replaced by 30% of the total volume.
- Minnow’s definitely needed bright lighting, so additional artificial lighting will be required.
- Soil to the bottom is better to choose dark. You can put small pebbles or sand.
- It is better to plant algae in such a way that the entire thickness of the water to the very bottom is well lit and the fish have enough space for games and swimming. The best plants are with small leaves. Elodea, hornwort, Ludwig, Vallisneria, dienophile, etc. are well suited. Duckweed can be settled on the surface of the aquarium.
- You can decorate the space of the aquarium with the help of smooth stones and snags.
In general, this species is unpretentious and recommended for maintenance even by inexperienced aquarists.
Minnow Fish Feeding
You can feed this species with a wide variety of feeds. It should be borne in mind that these fish are able to take food only from the surface of the water.
This is due to its anatomical features. Slices of food should not be too large.
The following types of food can be given to a fish:
- living – bloodworms, daphnia, tubule;
- granular – scraped beef heart;
- vegetable – white bread, steamed semolina;
- dry – Gammarus.
B vitamins can be added to dry food.
Minnow Fish Tank Mates
Minnow Fish are highly active and mobile, but at the same time loving and accommodating. They get along well with different fish.
The larger the flock, the more comfortable the representatives of this species feel. If there are less than 5-6 individuals in the flock, they begin to hide in secluded corners, lose their bright attractive color.
The Best Tank Mates for Minnow fishes are:
Chinese zebrafish are slower than other types of fish and cannot defend their territory, so it is better not to settle them along with minnows.
Tank Mates, You Should Avoid:
- Sumatran barbs;
- Aggressive Cichlids
Minnow Fish Breeding
There are 2 ways to breed these fish at home:
- You can get offspring right in the general aquarium. However, only minnows should live there. Representatives of this species usually do not touch fry and eggs, therefore, the number of young individuals will be high.
- You can put producers in a separate spawning aquarium. Its capacity can be about 20 liters, the quality and temperature of the water are the same as in the general aquarium. Mandatory presence of plants and aeration. The ground in spawning can not be laid.
To obtain offspring, 5 females and 2 males are placed in the spawning grounds and begin to feed them plentifully. After some time, each female lays about 300 eggs.
Adults are then recommended to return to the general aquarium but can be left in spawning. Fries will appear in 36–48 hours. A few days later they will be able to eat on their own.
You can feed them with the following foods:
- “Living dust”;
- mashed egg yolk.
As they grow up, daphnia and small cyclops are introduced into the diet.
Minnows have a disease that is unique to this species. It proceeds in the form of tumors that affect all parts of the body of the fish.
The first manifestations can be found on the upper lip. At first, the tumor resembles a small rounded seed, which may have a gray or black color.
Other symptoms of this disease are not noted. At the same time, the fish does not lose its appetite and mobility. Tumors are not contagious and pose no danger to other individuals from the flock.
With proper care, regular water filtration and high-quality feeding, the cardinal will delight the owner with its brightness, excellent health, and mobility
