Other Names (How it Got Its Names) Common names: Southern Variabilis Poison Dart Frog, Southern Variable Dart Frog. Variabilis = “variable,” named for the species’ wide range of color and pattern morphs. The “Southern” morph refers to populations from southern Peru, which show distinctive coloration compared to northern/local morphs. Characteristics Small arboreal dart frog with bold coloration. Active and visual, often perching on leaves and mid-level plants. Known for being one of the more adaptable Ranitomeya species in captivity. Recommended Vivarium Size Minimum: 18” x 18” x 18” for a pair or trio. Taller enclosures (24” high or more) preferred, with bromeliads and vertical climbing options. Provide live plants, leaf litter, cork, and multiple hiding areas. Temperature Daytime: 72–78°F (22–25°C). Nighttime: 68–72°F (20–22°C). Avoid temps above 80°F. Humidity 80–100%, with daily misting. Requires bromeliads or water-holding plants for tadpole transport. Size of Frog Adults: 0.75–1.1 inches (2–2.8 cm). Life Span 8–12 years in captivity with proper care. Feeding Diet: small insects — Drosophila melanogaster and D. hydei fruit flies, springtails, isopods. Feed daily; dust prey with calcium and vitamins several times weekly. Color/Pattern The Southern morph typically shows a bright yellow or green body with heavy black reticulated (net-like) markings. Limbs are usually blue or turquoise with black webbing. Pattern is less variable than northern/local morphs, with a more consistent reticulated look. Social Behavior Best housed in pairs or trios; small groups possible if space is sufficient. Males may call frequently; visual barriers reduce territorial stress. Not as aggressive as Oophaga, but still monitor group interactions. How to Determine Sex Males: smaller, slimmer, with soft buzzing/trill calls. Females: larger, rounder when gravid. Juveniles can be difficult to sex until maturity. How to Breed Provide film canisters, petri dishes, or bromeliads for egg laying. Males call to attract females; eggs are deposited on smooth, moist surfaces. Parents transport tadpoles individually to bromeliads or small water pools. Tadpoles feed on detritus and microfauna; some parental care may include egg feeding depending on locality. Metamorphosis occurs in ~2–3 months. 🌿 The Southern R. variabilis is admired for its clean, reticulated pattern and vivid blue legs, making it one of the more visually striking Ranitomeya morphs.
