Dendrobates azureus is one of the best known and most striking of the dart frog family. Their intense blue color and bold behavior makes them a favorite of hobbyists. These frogs have a very small and isolated distribution in small isolated patches of rainforest in the extreme south of Surinam. In appearance they resemble D. tinctorius and genetic evidence would suggest that azureus is not a separate species but is instead a morph or variant of tinctorius. However others have argued that their unique geographical location plus the likelihood of genetic isolation due to their restricted range are grounds for a unique species identification. Azureus can be among some of the larger dart frogs and as mentioned before are very active in the vivarium. They tend to be terrestial although younger frogs will climb quite actively. As they become sexually mature females will demonstrate aggression towards one another so a setup with a single pair or two males and a female are preferred. Breeding occurs primarily under the coco hut although we have found eggs on leaves before. The tadpoles are will attack one another so they are best housed individually. Azureus froglets morph out as tiny versions of their parents with full coloration. Our azureus pair was obtained from Quality Captives in November of 2004 and were in fact our second type of dart frog. They are housed in a 29 gallon standard vivarium. While it became clear that they were male and female, they took a long time (roughly 9 months) to produce fertile eggs. Since they were one of our first frogs that started breeding, the long time frame of infertile eggs was quite frustrating to say the least. However, they have 'figured it out' and produce good clutches on an ongoing basis.
