Ranitomeya uakarii ‘Gold Leg’
Intro
Ranitomeya uakarii “Gold Leg” (pronounced Ran-it-oh-may-ah you-car-ee) are orange, yellow and gold frogs, with black patterning. Being a Ranitomeya frog, Gold Legs are very small. These little fellas are rocket-fast and can be a bit on the shy side, but may warm up to you if you visit them through the glass a lot. They are diurnal like all Ranitomeya, so you won’t have to get up late to watch them. They should be active when you are! Only recorded as being a species in 2004 and imported shortly after, Gold Leg frogs are still very new to the hobby. These are an intermediate frog to care for, and confident beginners may do well with them if the correct research is done first.

Description
Gold Legs frogs are not too variable in their coloring. Their heads are solid vibrant orange or red, and this orange or red carries on down the back. Near the rump the color changes to a light yellow. Their legs are reflective gold. The heads of the frogs often have a black U shape on the nose, which continues into vertical strips down the length of the frog’s back. Typically a third stripe joins the others, starting on the crown of the head. Legs are spotted or blotched in black. This can vary somewhat in each individual frog. Small for a Ranitomeya, big females measure in at about 16mm, and males are typically slightly smaller. Females are consistent egg layers and therefore much wider or rounder than males. Gold Leg frogs share the common pearlescence of the Ranitomeya genus.
Distribution and Natural Habitat
Uakarii Gold Legs are native to Peru, in the Amazon basin. These frogs prefer to be off the ground and can be found living in bromeliads and leaves in the tropical rainforest. However, they like to lay their eggs in the leaflitter on the ground. Uakarii is considered by the IUCN Red List as “Least Concern”, making Gold Legs stable in the wild and fairly common to spot within their geographic range.
Behavior
Like all Ranitomeya, the Gold Legs frogs are diurnal meaning they are awake during the day. They are arboreal and live in the low hanging leaves of the jungles they inhabit. In the wild they are constantly foraging for small insects, invertebrates and arthropods on and around their plants. Some of the plants in the jungles contain various alkaloids and toxins, the micro fauna eat these plants and in turn get eaten by the frogs. This causes a downstream effect and these amazing frogs have evolved to harness the toxins as a means of self-defence. A combination of their striking colors and the toxins stored in their glands help ward off potential predators. In captivity the uakarii do not contain any of these toxins due to the diet provided to them. They don’t have access to the food they would be eating in the wild. Gold Legs live near streams and ponds, or right on the edge of slow moving water. While being frogs they are not very good swimmers and great care should be taken when making a suitable vivarium for them to live in. Once mature, the males will boldly perch in the open and call out to attract females. The uakarii call is soft. It sounds like a short, soft “buzz buzz” or “treep treep.” Mating males will buzz for up to 5 seconds when looking for a female. When a female selects a male, the pair will hop away to a nice quiet place, often in a bromeliad, and mate. For most uakarii the adult frogs are not too aggressive and a mixed group can be kept in a large enough vivarium. Be aware that this may change with individual frogs.
Life in the Vivarium
Like all dart frogs, Gold Legs require a humidity range of 70-100%. They can survive for brief intervals at 50% humidity if clean water is provided for them to soak in. You can place a bromeliad or small shallow dish of water in the enclosure or add a pond feature to achieve this. Remember, uakarii Gold Legs cannot swim well, so ensure that the water source is shallow and easy to get out of. The water level should be no higher than the smallest frog can sit in with his head and upper torso out.
Gold Legs thrive at temperatures near 21°C (70°F) but can survive a range of 18°C-27°C (65°F-80°F). Never exceed 29°C (85°F) as this can be fatal to the frogs. Generally a heat source such as a pad or light is not needed on a dart frog vivarium, apart from any lighting for plants. Do not rely on sunshine from a window, because the sun through the glass will heat up to extremely unsafe temperatures very quickly. Keep note of any air conditioning or heaters used in your home as well, as they may affect the temperature in your frog cage.
It is possible to house a single uakarii Gold Legs in a 7 gallon aquarium. We recommend a 30cmX30cmX45cm (12”X12”X18”) enclosure – but bigger is always better. This size vivarium is suitable to house 2-3 adult Gold Legs.
As juveniles you can house several Gold Legs together, however as they mature you may want to watch for aggression. In our experience Gold Legs can be housed in male heavy mixed groups, but if any fighting is observed you will be required to remove the offending frog. The size of the vivarium provided and the individual personalities of each animal will dictate how many frogs you can keep in an enclosure. It is common to keep a pair or trio of frogs in one enclosure. If you want to keep a group, add at least 1 gallon of space per additional frog.
It is common for a healthy Ranitomeya to live for 10+ years in a vivarium. Please consider this before deciding to take them home to your family. As with most amphibians they are considered a “hands off” pet similar to a fish. Due to their delicate and permeable skin, it is not advised to handle your frogs. The chemicals, oils and debris on your hands could prove fatal to your dart frog pet when it is absorbed through their skin. It is recommended that you wear powder free rubber gloves if you are required to handle your dart frogs. In an emergency, such as an escape from the enclosure, try to capture them as fast as possible (bare hands will do… if needed) as they will try to hide quickly, and unfortunately this will become fatal very rapidly.
Uakarii Gold Legs require small live prey to hunt. This is easily achieved by providing them with flightless or wingless fruit flies. Gold Legs will eat Drosophila melanogaster fruit flies. Springtails are also a wonderfully sized snack for fingernail frogs. The flies and springtails on their own are a poor nutritional source. We recommend “dusting” your fruit flies with a high quality vitamin and mineral supplement. We use and recommend Dendrocare all in one vitamin/mineral supplement. You can combine and use other supplements available to you, however please ensure you research what ratio or frequency you can supply vitamins as some can be lethal in high dosages.
It is recommended to build a bioactive vivarium for your dart frogs. This is achieved by introducing isopods and springtails into the environment. These little land crustaceans (no they are not insects!) will eat the decaying and decomposing bio matter as well as any excess feces in the vivarium. Some of these micro fauna will be eaten by your dart frog, as a little snack.
As with all our frogs, we do not recommend that you house multiple species or morphs together. Please supply each group with a vivarium to call their own.
Breeding in Captivity
If you have provided all the necessary parameters to keep your uakarii Gold Legs happy and healthy, they are considered easy to moderate to breed in a vivarium. This makes them a popular choice for many dart frog enthusiasts, but less common with beginners. Eggs will be laid in the leaf litter or in a bromeliad in a secluded location. Many hobbyists will place a film canister, on the floor of the cage in the leaf litter. No parental care will occur after eggs are laid so it is up to the handler to protect them. Typically 4-8 eggs will be laid at one time. The eggs take approximately 10-14 days to fully develop. The tadpoles will take approximately 60-80 days to fully metamorphosize into colorful little froglets.
Final Notes
Ranitomeya uakarii Gold Legs are stunning orange, yellow, and gold pearlescent frogs with a soft voice and a big attitude. Their moderate care level and ease of breeding makes them a lovely choice for any frog keeper. Beginners should be ready to do their homework and chat with us thoroughly, but these frogs can be kept by a novice or an expert keeper.
