Dear colleagues! Metinnis ordinary lives in South America, and in particular in the basins of the Paraguay and Amazon rivers.
The fish is kept mostly in dense vegetation and occasionally goes out on the lawn to swim. For the first time they brought this fish to the territory of the Soviet Union in 1970.
In ordinary metinnis, the body is rounded and flattened laterally, with scales of silver-steel color. The eyes of this aquarium fish are silver with a black vertical bar. The fish has a tall and straight dorsal fin, and the tail of the fish has the shape of a crescent.
The adipose fin in the mirror fish is rather long, and in the anal fin the elongated base. The back of the fish can be colored green, brown or blue-gray.
The sides can also be cast in different colors: bluish, green and yellow. Looking from what areas the fish, on its body on the sides may be thin black stripes and dark spots.
These strips run from the top of the fish to the sideline.
The fins of the fish are transparent in appearance and the abdomen is white. Males look slimmer than females and do not have a full abdomen. In addition, in females, the tip of the anal fin has a red dot.
At the male, the edge of the anal fin is arched. When spawning in males, the body turns red and golden.
In nature, this aquarium fish grows up to 15 centimeters in length, but in aquariums they are still smaller.
Metinnis ordinary, despite its medium size, does not belong to aggressive fish, rather, on the contrary, he is very peaceful and shy. Fish are schooling, so they are mainly kept in species aquariums in flocks numbering from 6 to 10 individuals in a flock.
But it can be hooked up and in the general aquarium, but neighbors should also be of the same size and habits. For metinnis need an aquarium of 200 liters, on the bottom of which lays a dark aquarium soil. In addition, hardwood aquarium plants are planted in aquas with metinnis, which they cannot eat.
In the role of decorative elements can act snags and stones, but provided that they do not contain calcium and magnesium compounds. The main requirements for the maintenance of metinnis:
- The lighting in the aquarium should be in the region of 0.5-0.7 W per liter;
- Aquarium water hardness: not more than 15 dH;
- temperature from 23 to 28 degrees;
- acidity from 6.5 to 7 pH;
- strong aeration and water filtration.
Just do not forget to replace weekly about 30% of the volume of water. The fish mainly feeds on vegetable feed. It is recommended to treat your pets with Brussels sprouts, scalded lettuce, nettles and dandelions.
Only 20% of the diet of metinnis should fall on animal feed, or replace it with a special food for herbivorous fish.
Metinnis are breeding at the age of more than a year, just by this period of their life the fish becomes sexually mature. Bred them in spawning, where the following conditions are met:
- water hardness not more than 4 dH;
- active reaction environment: 6.4-7.0 pH;
- water temperature: 26-30 degrees;
The minimum spawning volume is 200 liters and small-leaved plants such as javanese moss are placed into it. As a rule, young individuals are selected as producers.
But before you spawn a couple to spawn, you need to hold it separately for about 10 days and feed it abundantly with vegetable food. During one spawning, the female can sweep away from 300 to 1000 transparent eggs.
Eggs will sink to the bottom, or attach to plants. After spawning is over, the producers need to be deposited from the spawning aquarium.
The process of incubation of eggs takes four days, and even after 5-7 days the larvae independently swim and feed. Starter feed for young animals is Nauplii Artemia, small plankton, finely chopped lettuce and artificial food.
