Temperatures of 70-80º F during the day with drops as low as 65º F at night are recommended.
Being larger frogs, Azureus and Tinctorius require a good amount of floor space. Pairs of frogs should not be kept in tanks smaller than 10g, with larger tanks preferable (20, 20L). Small groups of frogs consisting of 2-3 males to a single female are ok. But multiple females are discouraged as female-female aggression, perhaps the most intense of all dendrobatid species, is a serious problem. Housing two sexually mature females can lead to the death of the non-dominant animal. This may not be the case in individual situations without the presence of a male, but is not guaranteed. Female aggression is much stronger than male-male or male-female aggression. Care should also be taken when introducing (or reintroducing) mature animals into established groups, when aggression can be greater.
Individuals can generally be sexed based on the size of the frog (females generally display greater length and girth) and the size of the forelimb toepads (the forelimb toepads of males are usually at least 2 times larger than the forelimb toepads of a female). Please note however, that these are generalizations, and may not always be the case with every frog. Froglets or sub-adults may be difficult to sex using these criteria as the differences may not always be present at younger ages. It has also been noted that some morphs of tinctorius do not clearly show these differences. Males do also call, which has been described as a soft buzz, but this may or may not be audible outside the tank.
