Species description
Geographical Origin and Habitat: Dendrobates tinctorius morph 'Lorenzo' is an extremely localized and rare color form of poison dart frog, native to the Sipaliwini savanna in the far south of Suriname, near the border with Brazil. Unlike other forest-dwelling populations, it inhabits 'forest islands'—isolated patches of humid rainforest surrounded by dry, open savanna grasslands. It lives in the humid understory, among the leaf litter layer of wet leaves, exposed roots, moss-covered rocks, and microhabitats created by fallen logs.
Taxonomy and Genetics: It belongs to the class Amphibia, order Anura, family Dendrobatidae, genus Dendrobates, and species tinctorius. The 'Lorenzo' morph represents a geographically isolated population that has developed and stabilized a unique, heritable color pattern. In the wild, the skin of these frogs contains toxic alkaloids secreted for defense, derived from metabolizing formic acid and other substances in their wild diet (ants and mites); captive-bred specimens are completely non-toxic.
Behavior and Habits: It has diurnal habits and exhibits an active, curious, and unusually bold behavior compared to other amphibians. It spends the day patrolling the ground for food. Males are territorial and use very soft, buzz-like vocalizations to attract females or deter rivals. Adult females exhibit strong territorial behavior and intrasexual aggression, engaging in actual physical wrestling matches to gain exclusive access to males.
Morphology: It is a medium-to-large poison dart frog for the family, with adults measuring between 4.5 and 5.5 centimeters (1.8 to 2.2 inches) in snout-to-vent length. Females are typically larger, longer, and rounder than males. The coloration is unique and spectacular: the back and sides are a glossy jet-black, interrupted by a white horseshoe or inverted 'U' shaped band on the dorsum. The front and hind limbs feature an intense cobalt blue or electric purple coloration, free of black spots.
Care, breeding and tankmates
Terrarium Setup: Requires a specific terrarium (minimum 45x45x45 cm / 18x18x18 inches for a pair). It is essential to set up a bioactive terrarium with a drainage layer (expanded clay) at the bottom, covered by a mesh and a humid substrate (coco fiber, peat, and sphagnum) topped with a thick layer of dry oak or magnolia leaves. The decor should include cork bark, driftwood, and live plants, especially bromeliads, which collect water in their leaf axils where the frogs deposit tadpoles.
Lighting and Heating: Requires moderate LED lighting to support live plant growth and a low UVB output (2-5%) to promote the general well-being of the frogs. The ideal daytime temperature must be maintained between 22°C and 26°C (72°F - 79°F). It does not tolerate high temperatures: values above 27-28°C (81°F - 82°F) can cause lethal heat stress in a short time. At night, the temperature should experience a physiological drop to 18-20°C (64°F - 68°F). Avoid dry heat sources.
Humidity and Hydration: Air humidity must be kept constantly between 80% and 90%, misting the terrarium twice daily with reverse osmosis or distilled water. The substrate should be kept damp but never soaked or muddy. Deep water must not be present since these frogs cannot swim and risk drowning. It is useful to provide a very shallow dish with a thin film of water (1-2 millimeters) placed under a cork hide.
Feeding and Supplementation: Feeds exclusively on small live invertebrates. In captivity, the diet is based on fruit flies (Drosophila melanogaster and D. hydei), springtails, dwarf isopods, and micro-crickets. The food must be dusted at every feeding with a pure calcium and vitamin D3 supplement, and once a week with a multivitamin complex containing preformed vitamin A, which is essential to prevent developmental and reproductive pathologies.
Compatibility: It is highly recommended to keep this species in pairs (male and female). Due to the intense territoriality and aggression of adult females, housing multiple females in the same terrarium leads to constant fighting and high stress. It must never be housed with other frog species or other morphs of Dendrobates tinctorius, to prevent hybridization and the transmission of pathogens.
Health and Common Diseases: Sensitive to fungal skin infections, including chytridiomycosis (caused by the fungus Batrachochytrium dendrobatidis), and systemic bacterial infections favored by poor ventilation or dirty conditions. Vitamin A deficiency causes spindly leg syndrome in tadpoles and neurological problems in adults. Metabolic Bone Disease (MBD) occurs in the absence of proper calcium supplementation.

The catalog's scalar value is 5 cm. The AmphiBIO v1 source reports a maximum adult measurement of 5 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
