Diamond Tetra (Moenkhausia pittieri) Eigenmann, 1920.
Tetra Brillintovaya or Almaznaya is one of the most beautiful representatives of the Kharacin family, discovered by the researcher Egeinmann in 1920 and already 10 years later occupied a strong position in amateur aquariums.
Endemic of Lake Valencia or Takarigua (Spanish: Lago de Valencia) in the state of Carabobo and Aragua in the north of Venezuela and adjacent water bodies.
Valencia is located between two mountain ranges and is the second largest lake in Venezuela. Water quality is usually very poor, mainly due to pollution from human life in agriculture and industrial production. Thus, there is a constant eutrophication (the process of deterioration of water quality due to excessive influx of so-called “biogenic elements” into the reservoir, primarily nitrogen and phosphorus compounds) and the associated water / algae bloom.
Studies have shown that fish species diversity has decreased by almost 60% from the middle to the end of the twentieth century. The diamond tetra lives in shallow, overgrown parts of the lake, as well as in several slow tributaries.
Most Diamond Tetras offered in stock trading are massively bred on Asian commercial farms.
Description: trunk in the form of an elongated oval, high and slightly flattened on the sides. There is a fatty fin, two-bladed tail.
The main color is yellowish with a red tint, the back may be gray-blue or brownish, and the belly is white, cast in silver. Fins are dark gray with white edging.
From the middle of the body to the tail stretches a bluish longitudinal strip.
The upper part of the iris is red. Scales over the body shimmer, so the fish is called Diamond / Diamond, although only mature individuals show beauty, the young are rather faded.
Tetra Diamond / Diamond (Moenkhausia pittieri) male.
Males are usually larger and less well-fed than females, with a larger proportion of reflecting scales that give a common name. They also have beautiful, enlarged ventral, dorsal and anal fins when they mature.
Males have a saturated purple tide, while in the female it is almost invisible.
Tetra Brilliant / Diamond (Moenkhausia pittieri) female.
The maximum standard length is 6 cm, the females are smaller.
Arrangement and parameters of the aquarium: A small group needs an aquarium of about 60 x 37.5 x 30 cm – about 70 liters.
Pretty adaptable look that will feel great in a variety of aquariums, although not very like bright lighting. But it looks great in densely planted aquariums, where it really shows intense colors.
Diamond or Diamond Tetra (Moenkhausia pittieri) schooling fish, which is well suited for keeping in a spacious common aquarium with dense vegetation around the perimeter, floating plants, free swimming space, subdued lighting and dark ground.
Behavior features demonstrate at a content of at least 7-8 individuals, and in a company of 10-15 relatives it becomes even more interesting: males flaunt themselves before females, fluffing up their tails and sparkling with their own diamond scales. The size of the aquarium is selected at the rate of 10-15 liters per pair of adult fish.
Water parameters: from 24 to 28 ° C, pH 5.5-7.0, dH from 5 to 12 °.
Diamond Tetra can also be contained in an aquarium with Amazonian biotope. Use river sand as a substrate and it is worth adding a few branched snags.
A few handfuls of dried leaves (beech or oak) will complete the re-creation of a natural look. Lighting should be quite dim.
Behavior and compatibility:
A good choice for a common aquarium. These are quite beautiful and peaceful fish, males grow to impressive sizes for TETR. These are good neighbors for most viviparous, rasbor, other tetras and peaceful inhabitants of the lower levels, such as the corridors or the Loricaria soma.
It can also be kept with most widely available gurus and dwarf cichlids.
Although she has a reputation for biting fins, this behavior can usually be corrected by keeping her in a flock of at least 6-8 individuals. When keeping the genus in such an amount, any squabbles usually occur in their group.
Like almost all tetras, he feels much better in the presence of individuals of the same species, and, as a rule, is a bit shy if kept in insufficient quantities.
Nutrition: in nature, it feeds on small insects and invertebrates, living in water or falling into it.
Easy to feed. Will eat everything that you can offer.
For a better condition and color – regular feeding of small live and frozen foods, such as bloodworms, daphnia and artemia, along with dried flakes and pellets.
Reproduction: may be in a similar way, like many other tetras.
You will need to take a separate aquarium. About 45x30x30 cm in size. Use very dim lighting and add clusters of small-leaved plants, such as Java moss or artificial spawning material (“washcloth”), to give the fish an opportunity to resist somewhere.
Or you can cover the bottom of the aquarium with a suitable mesh. The cells of which must be large enough so that the eggs pass, but small enough so that the producers cannot reach them.
Water in the spawning aquarium should be mild and acidic in the range of pH 5.5-6.5, GH 1-5, at a temperature of about 28 ° C. Filtering water through peat is useful. A small air filter sponge is all that is needed.
Breeding can take place in a group, with half a dozen individuals of each sex.
Alternatively, breeding may be in pairs. In accordance with this method, preliminarily males and females should be kept in groups separately. When the females noticeably replenish / spawn, and the males acquire their best color, choose the fattest calf from the calf and the best in color of the male and transplant them into the spawning aquarium in the evening.
They should start breeding the next morning.
Producers eat caviar and should be removed as soon as they spawn. Incubation for 24-36 hours, the larvae begin to swim freely in 3-4 days.
They should immediately be offered an infusoria – the main food during the first few days, until they are large enough to take micro-food or nauplia of artemia.
In the first 1.5-2 months, the young grow very rapidly, then more slowly and by 4-5 months reach the size of adults. The fry of the Diamond Tetra are prone to cannibalism, therefore, larger ones need to be transplanted to another container in a timely manner.
Capable of breeding in 8-12 months.
Lifetime Diamond / Diamond Tetra (Moenkhausia pittieri) from 3 to 6 years.
This kind of ugly duckling, which they usually sell in adolescent size / age. Considering the time, with good nutrition and content, it turns into a magnificent fish sparkling like a diamond.
A large flock of them in the aquarium with plants looks amazing.
