  • Bright green and black coloration
  • Moderately bold
  • Very easy to breed
  • Quiet call

Name: Dendrobates auratus 'Costa Rican Green and Black'. Commonly called the Green and Black Poison Dart Frog, the Mint dart frog (not to be confused with the mint form of Phyllobates terribilis), or the Costa Rican Poison Frog. The species is commonly referred to as 'CR or Costa Rican Auratus' in the United States frog hobby. Simply calling the species 'auratus' is fairly common, as well.

Recommended Vivarium Size & Setup: A 10 gallon aquarium is suitable for a single Dendrobates auratus 'Costa Rican Green and Black', but Josh's Frogs recommends a 20H or 18x18x18 glass terrarium for 1-3 frogs. Auratus will not climb as much as other varieties of dart frogs, and prefer a horizontally oriented tank. Costa Rican auratus seem to appreicate a water feature, such as a small pond.

ABG mix or Josh's Frogs Dart Frog BioBedding in conjunction with our other bioactive layers (false bottomsubstrate barriersphagnum 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 85 degrees, but prefer temperatures in the low to mid 70s. Temperatures over 85° are dangerous.

Monitor temps with a digital thermometer.

Humidity: Like most poison dart frogs, auratus 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 to Dendrobates auratus 'Costa Rican Green and Black'.

Auratus in particular seem to enjoy a wetter environment and higher ambient humidity levels than other species of poison dart frogs, and will be more active in a more humid environment, especially when provided with a water feature. In the wild, auratus are commonly found in association with streams.

Size: Adult female Costa Rican Auratus are larger, measuring approximately 1.5 inches. Male auratus are a bit smaller, averaging about 1.25 inches at maturity.

All of the Dendrobates auratus 'Costa Rican Green and Black' froglets Josh's Frogs sells are well started juveniles, and measure at least 5/8 inch long.

Age: Dendrobates auratus 'Costa Rican Green and Black' is capable of living well over 20 years in captivity under ideal conditions, although a lifespan of 10 years is more common. In the wild, it is thought that galacs may live 4-6 years.

All Green and Black Auratus for sale at Josh's Frogs are well started juveniles, and are 2-3 months old.

Feeding: Like most poison dart frogs, auratus prefer smaller foods. All of the 'Costa Rican Green and Black' froglets Josh's Frogs sells will readily eat Drosophila melanogaster fruit flies. Adult Dendrobates auratus 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 auratus 'Costa Rican Green and Black' is not sexable until 10-12 months of age, and even at that age visual sexing is very difficult. Male auratus tend to be smaller than females, which often appear both longer and wider. Males also tend to have wider front toe pads and a less defined back arch than females. Josh's Frogs sells 2-3 month old juvenile Costa Rican auratus that are not sexable unless otherwise noted.

Color/Pattern: A typically green and black poison dart frog, Dendrobates auratus 'Costa Rican Green and Black' is not very variable. Splotches of black constrast nicely with a bright green. As Costa Rican auratus age, their colors often change a bit as well. The intensity of the green can vary a bit, from a yellowish green to a forest green. The green/black pattern typically resembles camo, but occasionally a spot or stripe can make itself apparent. On rare occasions, reticulated individuals pop up.

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.

Social Behavior: These frogs do well housed in groups their entire life, as long as enough space is provided. Josh's Frogs recommends approximately 10 gallons per frog.

As they reach sexual maturity at 10-12 months of age, the social dynamic in a group of Dendrobates auratus may change, and females may eat each other's eggs. Female D. auratus 'Costa Rican Green and Black' may fight with each other over a mate. For that reason, many breeders recommend keeping auratus in pairs as adults. In our experience at Josh's Frogs, generally this aggression is minor, and auratus make a great group frog. Josh's Frogs strongly recommends against housing different species/morphs of dart frogs—for the health of your pets, please avoid mixing!

Breeding: Costa Rican Green and Black auratus are very easy to breed. Sometimes they lay eggs frequently, only to go months before laying another clutch.

Like most Dendrobates, eggs are deposited on a smooth broad leaf, or on a petri dish under a cocohut. Most egg clutches consist of 4-6 eggs. The eggs hatch into tadpoles, which then take 60-80 days to complete metamorphosis into miniature versions of the adults.

Josh's Frogs recommends purchasing multiple frogs if you are interested in breeding them – this greatly increases the chances of getting a pair (male and female).

Natural Range: Dendrobates auratus 'Costa Rican Green and Black' is native to Costa Rica. The exact locale of this large form of green and black auratus is unknown, and it is likely several different populations of green and black frogs exist. Generally found in humid lowlands, Costa Rican auratus seem to thrive in heavy layers of leaf litter, and are often found near streams or creeks.

History in the Hobby: Many different forms of auratus are present in the hobby, predominantly from Panama. Costa Rican Green and Black auratus are unique in that they are the only common morph originating from Costa Rica. Imported in the late 1980s and early 1990s, Costa Rican auratus are no longer imported in large numbers.

Ordered 4, should have gotten more

Of course these little guys arrived healthy, and readily eating. They are so beautiful to look at, they were on my top three breeds i HAD to have. I like their bright coloration even more than some of the metallic looking types. Its a true bright color. I wish i would have ordered more than four!

Ryan

Amazing little frogs!

I couldn't be more happy with these guys! Striking colors! I used warehouse pickup to buy two of them and they were healthy upon pickup and began eating right away. I will be purchasing more dart frogs from Josh's in the future!

Ordered 3 frogs and they came in yesterday. Well packed, fast shipping. Looked in great shape when I let them out. Have only seen two day, but I'm sure the other is hiding somewhere :) Love, love the colors :)
