Other Names (How it Got Its Names) Common names: Vanzolini’s Poison Dart Frog, R. vanzolinii. Named after Brazilian zoologist and composer Paulo Emílio Vanzolini. Part of the Ranitomeya genus, known for small, brightly colored dart frogs with parental care behaviors. Characteristics Small and delicate frog with bold black, yellow, and sometimes orange markings. Known for unique parental care: males transport tadpoles, and females feed them with unfertilized eggs. Considered one of the rarer and more sought-after Ranitomeya species. Recommended Vivarium Size Minimum: 18” x 18” x 18” for a pair or trio. Taller enclosures (24” high or more) with bromeliads and climbing space are ideal. Provide dense live planting, cork, and plenty of leaf litter. Temperature Daytime: 72–78°F (22–25°C). Nighttime: 68–72°F (20–22°C). Avoid temps above 80°F. Humidity 80–100%, maintained with frequent misting. Bromeliads or water-holding plants are essential for tadpole care. Size of Frog Adults: ~0.75–1 inch (2–2.5 cm). Life Span 8–12 years in captivity with proper care. Feeding Diet: small insects — Drosophila melanogaster and D. hydei fruit flies, springtails, and isopods. Feed daily; dust prey with calcium and multivitamins several times weekly. Color/Pattern Striking black base with bright yellow or orange dorsal markings. Limbs are typically blue to turquoise with black reticulations. High contrast pattern makes them visually stunning. Social Behavior Best housed in pairs or trios; larger groups can become stressed or aggressive. Known for cooperative parental care within pairs. Males may call with a soft buzzing trill. How to Determine Sex Males: smaller, slimmer, develop calling behavior. Females: larger, fuller-bodied, especially when gravid. Juveniles are very difficult to sex until maturity. How to Breed Provide film canisters, bromeliads, or leaf axils for egg-laying. Males call to attract females; eggs are laid on smooth, moist surfaces. Males transport tadpoles to bromeliads; females provide unfertilized eggs as food. Tadpoles metamorphose into froglets in ~2–3 months depending on conditions. 🌟 Ranitomeya vanzolinii is considered a collector’s dart frog because of its rarity, striking colors, and fascinating parental behaviors.
