Name: Dendrobates leucomelas 'Guyana Yellow'. Leucomelas literally translates to white and black, due to the original specimen described presumably blanched of color from preservation. In the hobby, Dendrobates leucomelas are often called bumblebee dart frogs, yellow banded poison dart frogs, leucomelas, or simply 'leucs'. The 'Guyana Yellow' tag simply refers to the country of origin, and the fact that this morph has more yellow coloration than other leucs from the same area.

Recommended Vivarium Size & Setup: A 10 gallon aquarium is suitable for a single Dendrobates leucomelas 'Guyana Yellow', but Josh's Frogs recommends a 20H or 18x18x18 glass terrarium for 1-3 frogs.

ABG mix or Josh's Frogs Dart Frog BioBedding in conjunction with our other bioactive layers (false bottom, substrate barrier, sphagnum moss and leaf litter) are great substrate options for your dart frog setup! Both of these mixes support microfauna populations, which help break down waste and mold within the tank.

Temperature (°F): They can tolerate a temperature range of 65 to 80 degrees, but prefer temperatures in the low to mid 70s. Temperatures over 85° are dangerous. Measure temps with a digital thermometer.

Humidity: Like most poison dart frogs, Guyana Yellows prefer a humidity range of 70–100%, but can tolerate humidity down to 50% for short periods of time if the frogs have access to water. Low humidity levels, especially without access to water, can quickly be fatal. Measure humidity with a digital hygrometer.

Size: Adult female leucomelas are larger, measuring in at approximately 1.5 inches. Male leucs are a bit smaller, averaging about 1.25 inches at maturity. In our experience, Guyana Yellow leucs tend to be a bit larger then most other Venezuelan leucomelas. All of the Dendrobates leucomelas froglets Josh's Frogs sells are well started juveniles, and measure approximately 5/8” long.

Age: Dendrobates leucomelas is capable of living well over 20 years in captivity under ideal conditions, although a lifespan of 10 years is more common. All bumblebee dart frogs for sale at Josh's Frogs are well started juveniles, and are 2-3 months old.

Feeding: Like most poison dart frogs, leucs prefer smaller foods. All of the bumblebee poison dart frogs Josh's Frogs sells will readily eat Drosophila melanogaster fruit flies. Adult Dendrobates leucomelas will readily consume Drosophila hydei fruit flies and pinhead crickets. All ages of poison dart frogs will enjoy springtails and isopods. All feeder insects should be dusted with a vitamin/mineral supplement.

Sexing: Dendrobates leucomelas 'Guyana Yellow' is not sexable until 10-12 months of age. Male leucs tend to be smaller than females, which often appear both longer and wider. Josh's Frogs sells 2-3 month old juveniles that are not sexable unless otherwise noted. For more information on sexing poison dart frogs, please visit our How-To Guide on Sexing Poison Dart Frogs.

Color/Pattern: A very variable poison dart frog, all Dendrobates leucomelas 'Guyana Yellow' are mostly yellow and black in color with a varying degree of black spots and bands. The yellow can range from a very bright yellow to an orange color in some individuals. Most leucs born orange will turn yellow with age. Josh's Frogs does not recommend, support, or endorse line breeding as we believe this leads to weaker captive animals and nature has done a wonderful job of creating an amazing variation in color and pattern of poison dart frogs already.
