The native land platidoras (Platydoras costatus) are tropical reservoirs of the South America. These catfishes have been nicknamed "grumbling" because of specific sounds published by them by means of swimming bubbles and chest fins. Naturally such sounds help fishes to find to themselves the partner, and also to warn about danger. In an aquarium platidoras them publish during stressful situations or at territorial disputes. In spite of the fact that they are very extended also them for a long time and successfully plant, some parties of their life are a little studied.
Trunk platidoras massive, wide and flattened, narrowed to a tail in the field of a back fin. The body and a head are covered by the reservation - firm bone 28-31 plates. On each side thorns are located. On branchiate covers there are sharp ledges. On the big head there are the big eyes, the stretched large mouth and two pairs dark brown moustaches on the bottom and top jaws, the Basic окрас trunks dark brown. From above, along all body, there pass two longitudinal light yellow strips. They begin from the end of a tail fin, and converge on a head between an eye. The paunch, the bottom part of a head and a fatty fin are painted in is light yellow colour. A tail fin small, brown with a yellow border. Back large, it is painted in yellow colour. On it there passes a slanting strip of dark brown colour. Chest fins big, well developed, dark brown colour with a yellowish fringing. On them the small thorns which are coming to an end with a sharp hook are located. For this reason at catching platidoras (Platydoras costatus) it is desirable to use plastic or other capacity, but only not a net, the small fish can strongly get confused and at disentangling it is possible to prick strongly thorns (a prick very painful). At the slightest danger of a small fish arrangedт fins. Sexual differences: the male is more harmonous, less and is more contrastly painted; the female at the slightest danger becomes dark brown, and only the very narrow strip of thorns remains light yellow. In the nature at length can reach to 22 sm, in an aquarium, as a rule, grow no more than 15 Life expectancy in an aquarium of 12 years see.
Platidoras (Platydoras costatus) - night, peace and very amusing small fish. As activity at it comes at night, to observe it it is possible during feeding, when it picks on all aquarium. In the afternoon, as a rule, hides in various shelters, but sometimes she can be seen during rest on the places opened to the review (for example, between glass and the filter). Platidoras (Platydoras costatus) live in the bottom sheets of water.
To contain Platidoras it is not difficult. The aquarium with volume not less than 80 l with thickets of live plants and various shelters is necessary. Prefers the muffled illumination and a soft ground (sand, gravel).Platydoras costatus gets on with various kinds of fishes (an exception very small small fishes). Water parametres: rigidity 2-15 °, рН 6,0-7,5, temperature 22 - 26°С. The filtration, aeration, a channel and weekly substitution to 30 % of volume of water are necessary.
Striped platidoras (Platydoras costatus) in food uses a dry, vegetative forage (20-30 %), but the preference gives live (tubifex, bloodworm, small shrimps, hearts, small slices of meat or fish). It is inclined to a gluttony. In an aquarium sometimes there are very artful individuals: instead of with other representatives of the kind to collect a forage from an aquarium bottom, they emerge on a surface, turn over a belly up and start to collect a forage from a water surface.
The aquarium is necessary for spawning platidor (Platydoras costatus) with the muffled illumination in capacity from 100 l and active aeration. Various shelters (without sharp sides), floating plants (for example, riccia) are necessary. Water parametres: rigidity to 6 °, рН 6.0 - 7.0, temperature 25 - 27°С, the water level should not exceed 20 see. Before spawning it is necessary to contain 7-10 days manufacturers separately from each other, to feed with a live forage and fry catfishes. The male builds in spawning a nest in diameter from 3 to 10 sm from leaves of floating plants or postpone caviar in ground poles, pasting to a substratum. Spawning occurs to use pituitary suspensions of a sterlet and bream. The female striped platidoras (Platydoras costatus) throws to very sticky 300 berries. After the termination of spawning of manufacturers removed. The incubatory period 48-72 hours. At first larvae are at the bottom in a dark place. To float and eat fry Platydoras costatus begin for 5-6 days. A starting forage: a live dust,nauplii of Artemia,a microworm. Grow very slowly.Sexual maturity reaches in 2 years.
