1- Phyllobates bicolor, also known as the black-legged poison frog, bicolored dart frog :
Phyllobates bicolor, also known as the black-legged poison frog, bicolored dart frog or neari in Choco, is the second-most toxic of the wild poison dart frogs. This species obtained its name due to its normally yellow or orange body with black or dark blue hindlegs and forelimbs below the elbow. It lives in the lowland forests in the Chocó area in western Colombia, along the San Juan River.
In this species, the male transports tadpoles adhering on its back.
Endangered (IUCN 3.1)
(Duméril and Bibron, 1841)
Phyllobates bicolor is one of the largest poison dart frogs. Males can reach a length of 45–50 mm from snout to vent, while the slightly larger females reach 50–55 mm in length from snout to vent. P bicolor ranges in color from earthy orange to pure yellow in coloration, often with a blue or black tinge on their legs, hence their name. They are smaller and more slender than their close relative, Phyllobates terribilis, and can resemble juvenile or subadult P. terribilis frogs. They also bear a resemblance to D. leucomelas, particularly the "netted" color morph of D. leucomelas.
While its toxicity is weaker than P. terribilis, P. bicolor is still a highly toxic animal, one of the few frogs confirmed to have caused human fatalities. Just 150 micrograms of its poison is enough to kill an adult human. This frog is often heated over a flame to make it "sweat" the liquid poison for hunting darts. The poison causes death by respiratory and muscular paralysis. Research is being conducted to determine medicinal uses for this batrachotoxin. As with all dart frogs, captive-raised individuals are not toxic; the animals require chemicals found only in their wild food sources, mainly insects. In captivity, these chemicals are not available to them from their food sources.
Like many of the Phyllobates genus, P. bicolor is mostly terrestrial, only taking to the trees when rearing young. Most are solitary animals, however wild groups can be found occasionally. Unlike many frog species, both males and females can be vocal, producing high-pitched, bird-like calls. The black-legged poison dart frog is mostly diurnal, retreating into the cover of the leaf litter at night. While most individuals are solitary, during the wet season, P. bicolor frogs, like all dendrobatids, gather in large breeding groups. One of the more dedicated of parents among anurans, P. bicolor males carry their tadpoles on their backs. The tadpoles stick to the mucus on the backs of their fathers, and are transported to puddles. There they are fed and protected until they become froglets, at which point they are completely independent, and leave to begin their adult lives.
Captive care :
Care for P. bicolor is similar to P. terribilis, except P. bicolor can be kept in a slightly smaller enclosure.
P. bicolor can sometimes be kept in groups in captivity.

1- Scientific. Name: Phyllobates bicolor (D UMÈRIL & B IBRON , 1841)
courtesy to : www.dendrobase.de/index.php
The generic name Phyllobates comes from the Greek words "fyllo" (= leaf) and "bates" (= runners). The combination "Blattläufer" (Blatteiger) refers to more ground-oriented habitat of the species in the Krautschicht of the rainforest. The epithet bicolor comes from the Latin (bi- = two, color = color) and refers to the two-color body coloration with yellow trunk and green-trimmed limbs.

size : Great Phyllobates style with a SVL of 32-42mm. The weight of adult male is 4.5 g.
Yellow to orange ground color with green to black legs. The skin on the back can be easily granulated but is smooth in most animals.
Age : up to 6 years
with about 12 months. The first scrims are often of inferior quality (fungal). From the second to the third year production is highest.
very active and curious frog, almost always see. Deadline very gladly (unfortunately often too gladly, tends slightly to fatigue)

Attitude in the terrarium :
Terrarium / Facility:
Rainforest terrarium from 50x50x50cm
automatic irrigation and fog system recommendable
Tags 23-26 ° C, lower at night by 3-4 ° C
Minimum annual temperature fluctuation (1-2 ° C)
70-80%, at noon to 70%, in the morning and in the evening 100% (fog)
Usual small and medium-sized animal animals
Drosophila, Micro-Heimchen (also somewhat larger), jumping tails, meadow plankton
For the breeding the pairwise attitude is recommended. However, group management is quite possible. In the pool (70x70x70) depicted here live a total of 9 animals, which regularly produce offspring. In small groups, however, it must be ensured that there can be fighting between female animals.
Tips for breeding:
puts up to 15 eggs
Ovulation of the eggs about 13-14 days (at 21-23 degrees)
Rearing the burbot better individually, since with too little food cannibal. With 3-4 times daily feeding also group rearing is possible.
