Conditions of detention
Thayeria CrankbandedIt is a very agile, peaceful and a little shy fish. During swimming, the body position is at an angle, and the fish sways slightly. The aquarium should be covered from above, because due to its timidity, the tayeriya can jump out of it. It is advisable to keep this type of fish in a pack with at least 10 individuals.
Perhaps the joint content with peaceful aquarium fish of other species that have similar sizes. Prefers to stay in the upper and middle layers of water. An aquarium with a length of 80 cm, with a variety of shelters, as well as aquarium plants that are planted along the walls, is suitable for a teyeriya krivopolos. In addition, it is important to take care of the free space necessary for swimming.
As soil, river sand is suitable. Lighting should be diffuse and dim. The optimal water parameters for the content of tetra-penguin: hardness - 6–15 °, temperature - 23–28 ° C, pH - 6.0–8.0. Powerful filtration should be ensured, since taeiria is sensitive to insufficiently clean water, as well as aeration and substitution of 1/3 of the total water volume weekly. For teyeriya krivopolosa need live food, such as artemia, daphnia, bloodworm, which the fish collects from the surface. In the natural habitat, tayeria feeds on invertebrates, worms, insects, and crustaceans.
Thayeria crippled (Thayeria boehlkei Weitzmann), a haracin family fish. It lives in the Amazon basin.
Another name is "Tayeria Oblikva" or Tetra Penguin. But the real “penguins” are much larger (8 - 9 cm), and the broken black line on the body begins under the dorsal fin, obliquely crosses the body to the base of the caudal fin and then descends into its lower lobe.
T.boehlkei, aptly nicknamed the "stick" by aquarists, is one of the most original in the coloring and habits of the inhabitants of indoor ponds
The body is low, elongated, laterally compressed, up to 6 cm long.
Thayeria is not rich in colors.
The only adornment of the body is a wide velvet-black strip, starting at the gill covers and extending along the body to the end of the lower lobe of the caudal fin, resembling a hockey stick in shape. The general background of the body is silver-green, the back is darker than the abdomen, the fins are transparent, colorless. Sexual dimorphism is practically not expressed. Males are somewhat slimmer and slightly smaller than females.
Thayeria Cranioids - peaceful, schooling fish, get along well with other small tetravoid fish. Swim at the upper and middle levels.
The conditions of keeping the fish are unpretentious. For an adult couple, 6-8 liters of settled tap water with a total hardness of 5-10 degrees or more, PH = 6.8-7.0, is quite enough. For decorating a pond with tierias, any plants suitable for the taste of the aquarist and the parameters of the water are suitable.
The bottom is covered with coarse sand or gravel, if possible of a dark color - against its background the fish look more spectacular. Water temperature is recommended in the range of 22 - 24 degrees C.
Watching a flock of "sticks" is very funny: frozen motionless upside down, the fish seem to be preparing to jump, but at the slightest danger signal (a careless movement of the hand near the glass of the aquarium) they amicably and swiftly hide in the thickets of plants, and having calmed down, they re-occupy the former position.
Temperature: 72 ° - 82 ° F / 22 - 28 ° C Acidity (pH): Must be between 6.0 - 7.0. Hardness: up to 15 ° H.
Representatives of this species can be fed with small insects, worms, crustaceans and other zooplankton. For good health and a beautiful color, it is recommended to regularly feed small living organisms and frozen foods such as bloodworms, daphnia and artemia, as well as dried cereals and granules.
The sexually mature tetra penguin becomes one year old.
For fish breeding, it is necessary to prepare spawning with a volume of 20 liters or more (for 1 pair of fish). At the bottom of the spawning grounds, a separator grid should be placed and several bushes of plants with small leaves should be planted. Lighting should not be bright.
The parameters of water in spawning are as follows: temperature 26-28 ° C, hardness dH 4-8 °, acidity pH 6.2-6.4.
Before landing for spawning, producers are kept separately and plentifully fed with various feeds for 2 weeks.
Fish are released into spawning in the evening, and in the morning hours spawning begins. Males chase the females, striking with their abdomen on their body, thereby knocking out a portion of caviar from them, which they immediately fertilize. The spawning process continues for 2 hours.
During this time, one female spawns about 1000 eggs. It should be said that most of the caviar dies due to the fact that it was not fertilized by the male. Immediately after spawning, the producers are sedimented, and most of the water in the spawning is replaced with fresh. Spawning darken.
Caviar is incubated for 24 hours, and after 3-4 days, the fry begin to swim and eat. Starting dust for them is live dust, rotifers, mashed egg yolk. After 10 days, they begin to give artemia. With a balanced diet, fry grow very quickly and in a month reach a size of 1 cm.
The life expectancy of a tetra penguin in aquarium conditions is about 5 years.
Behavior and compatibility with other fish
Tetra penguins are peaceful fish that will not compete with active or larger neighbors in the aquarium. Ideally, these fish can be kept with other representatives of South American species. For example, tetra penguins can be kept with Hemigrammus or Hyphessobrycon tetras, pencil fish, Apistogramma, and other small cichlids, Corydoras, and Loricariids. Groups of these fish can also be kept with smaller parses (rasboras), barbs (barbs), Anabantoids and West African apistograms (dwarf cichlids), for example, Pelvicachromis.
It is recommended to buy these fish in a group of 6 or more individuals. Preferably, the group consists of 10 or more individuals. These fish belong to the flocking species, and it is desirable that they be in the company of their own kind. Any potential conflicts between representatives of different species will be exhausted. fish will be concentrated on squabbles among themselves. Tetra penguins will look great if you follow these recommendations.
