The Dendrobates tinctorius "Tumucumaque - Peacock" is a highly sought-after, vibrant morph (color variation) of the dyeing poison dart frog, known for its striking blue and black markings that sometimes have yellow or orange accents.  

Key Characteristics

Coloration: Displays a beautiful mosaic of bright blue, black "peacock" circular patterns, and sometimes yellow or orange accents. These circular patterns are often more pronounced on younger frogs. Size: A relatively large dart frog, with females measuring up to 2 inches (50mm) and males slightly smaller.

Origin: This specific morph is named after the Tumucumaque Mountains in the Amapá state of Brazil, within a protected biodiversity corridor.

Status in the Hobby: It is considered a newer addition to the US hobby and is highly valued. However, the original wild specimens were reportedly exported without authorization from Brazil, making it a "smuggled" locality, and ethical breeders in the hobby now work with captive-bred (F1 or later) lines.  

Care and Habitat

 Like other Dendrobates tinctorius morphs, the "Tumucumaque - Peacock" is diurnal (active during the day) and primarily terrestrial, spending most of its time in leaf litter, but it will also climb vegetation.

Housing: Due to territorial and aggressive behavior (especially female-to-female aggression), they are typically best housed in a large vivarium as a sexed pair. A trio is generally not recommended. 

Environment: Requires a high-humidity environment (75-100%) with good ventilation and a temperature range of 70–80°F (21–27°C) during the day.

Water: They are poor swimmers, so any water features in their enclosure must be shallow with easy exit points. Diet: In the wild, their diet of specific insects makes them toxic. In captivity, their diet consists of readily available, non-toxic live insects such as fruit flies, springtails, and tiny crickets. Captive-bred frogs are not poisonous.  

In the Vivarium This morph is a stunning display animal, and hobbyists enjoy creating naturalistic vivariums to showcase their vibrant colors and active personalities. They are relatively hardy when provided with the correct environment and care.
