The frogs are 25-30mm wide with the main difference is found between the sexes. Females few millimeters larger than the males. The animals all have a blue colored belly with a black spot pattern. The hind legs are green, blue or green-blue. The animals have a lining that from the hind legs, runs along above the eyes to the nose where the lines of both sides together. This lining is the most variable color, and be found in green, yellow, orange and red. From the groin is a line halfway to present the side of the animal. This line is often lighter in color than above, with a real red color is not found. On the upper arms has in many instances also have a yellow spot to take war. Not all animals have this spot. Sometimes there is in the middle of the back spots a pattern in the yellow or orange color and very rare to bluish green.

Geographical variation:

There are no real variations of this species known. Within the known populations, the color and pattern vary greatly. In the hobby of animals are sometimes sold as such a specific color. This is only based on commercial gain as the orange or red animals are more popular and people can ask a higher price. These animals will be just as easily produce offspring in all colors.

Call: A vibrator that about 40 seconds and can last even longer. The call is a bit like that of the Dendrobates leucomelas, but the tone is a little higher.

Distribution:

The north of San Martin, Peru, near Tarapoto. These species are found in the lowlands to about 1100 meter altitude.

Ecology:

H. azurieventris is a real bottom dweller who is in the nature of love among the leaves, stalks and often in burrows among rocks. In nature they are also often difficult to find. Larvae in this habitat are deposited in small pools in tree trunks and leaves. These pools contain than 1 or 2 at most larvae per pool.

The terrarium:

Hyloxalus azureiventris should be kept in a so-called jungle terrarium. 50x50x50 cm is large enough for a couple. For a group of 4 or 5 animals, think of a tank of 100x50x50 cm minimum, preferably larger. Furnish water-absorbent material on the walls (eg fern root) and a houtstronkje. Some plants such as bromeliads, etc. Marantaceae complete the installation. One part water, the larvae go where they can bring is also recommended. And everything moist. Differ are not demanding animals.

Temperature:

The temperature may fall between 22 and 25 ° C during the day. At night the temperature may drop several degrees. Preferably not below 18 ° C. Long time temperatures above 28 ° C are to be avoided.

Group / pairs:

Pairwise is recommended because these animals are free from aggressive peers. Females will eat each other's eggs, that is if they put the first place to come. When several men held together mostly unsuccessful mating means that no eggs are deposited. 
For some, the successful breeding in groups, but the numbers of offspring than much lower. In flocks they are extremely productive.

Eggs:

The clutch consists of 10-17 eggs, which develop in 10 days and is fanatically guarded by the male. The eggs are light in color, the jelly is often opaque. The eggs after laying often look as if they are bad. Within 24 hours you can develop however you perceive. Do not be too premature to Hide clutches that look bad.

Other breeding information:

If food they take fruit flies, but also young crickets and many other types of small insects (meadow plankton). If the males to their 40 sec. constant, audible sound heard mating calls are coming clutches. Once there, the male these clutches are almost constantly monitor. During this time the male will not call. Get your four-six road you can often within 48 hours expect a new clutch. Only to have them here because you can be exhausting the female. The clutches are also getting smaller because fewer mature eggs available to the female. 
The eggs are both bromeliad leaves and in holes, like a petri dish under a half coconut shell, disposed. The larvae are the male brought to the water and can be reared together. Sometimes the male will not all larvae in the same piece of water off. Possibly this has to do with the amount of water. It is therefore sometimes necessary to provide multiple outlets ponds. Males and larvae on the back keep walking around until they die are indeed observed. This is best avoided so. 
The larvae are on a diet of nettle leaves or spinach and visvoerers opgroeien.Na a quick six weeks the larvae metamorphose into small frogs over one cm. The young frogs grow very quickly into adult frogs. Some 3 months after metamorphosis can go all males begin calling. Females make sure 2 times as long to be juveniles. 
Sexes in adult animals quite well to distinguish when you look at the size and build. The women are few millimeters are usually much larger and more robust in the bul
