Name: Dendrobates auratus 'Nicaraguan Green and Black'. Commonly called the Green and Black Poison Dart Frog. The species is commonly referred to as 'Nicaraguan Green and Black' in the United States frog hobby. Simply calling the species 'auratus' or 'Nic auratus' is fairly common, as well.


Recommended Vivarium Size: A 10 gallon aquarium is suitable for a single Dendrobates auratus 'Nicaraguan Green and Black', but Josh's Frogs recommends a 20H or 18x18x18 Vivarium for 1-3 frogs. Auratus will not climb as much as other varieties of dart frogs, and prefer a horizontally oriented tank. Nicaraguan Green and Black auratus seem to appreicate a water feature, such as a small pond. Not sure how to set up a vivarium? Please watch our video on How to Set Up a Vivarium.


Temperature: Dendrobates auratus 'Nicaraguan Green and Black' can tolerate a temperature range of 65 F to 85 F, but prefer temperatures in the low to mid 70s. Temperatures over 85F are dangerous.


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 'Nicaraguan Green and Black'. Auratus in particular seem to enjoy a wetter environment and higher ambient humidity levels vs 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 Nicaraguan Green and Black Auratus are larger, measuring in at approximately 1.5 inches. Male Nicaraguan Green and Black auratus are a bit smaller, averaging about 1.25 inches at maturity. All of the Dendrobates auratus 'Nicaraguan Green and Black' froglets Josh's Frogs sells are well started juveniles, and measure approximately .75-1” long.


Age: Dendrobates auratus 'Nicaraguan 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. I had a friend who had a pair of auratus still breeding after keeping them for 27 years, and they were wild caught adults when he received them in the early 1990s! In the wild, it is thought that auratus 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, Nicaraguan Green and Black auratus poison dart frogs prefer smaller foods. All of the Green and Black auratus dart frogs Josh's Frogs sells will readily eat Drosophila melanogaster fruit flies. Adult Dendrobates auratus 'Nicaraguan Green and Black' 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. For more information on what poison dart frogs can eat, please visit our How-To Guide on Feeding Poison Dart Frogs.


Sexing: Dendrobates auratus 'Nicaraguan 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 Nicaraguan Green and Black auratus 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 typically green and bronze poison dart frog, Dendrobates auratus 'Nicaraguan Green and Black' is not very variable. Varying amounts of black ot brown to bronze constrasts nicely will a bright, forest green. Nicaraguan Green and Black auratus have a more metallic green coloration than other auratus morphs. 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: Dendrobates auratus 'Nicaraguan Green and Black' 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 'Nicaraguan 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! Josh's Frogs recommends purchasing multiple frogs if you are interested in breeding them – this greatly increases the chances of getting a pair.


Breeding: Nicaraguan Green and Black auratus are relatively easy to breed. Sometimes they lay egg frequently, only to stop and 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. For more information on breeding and raising poison dart frogs, please visit our How-To Guide on Breeding Poison Dart Frogs.


Natural Range: Dendrobates auratus 'Nicaraguan Green and Black' is native to Nicaragua. Generally found in humid lowlands, Nicaraguan Green and Black auratus seem to thrive in heavy layers of leaf litter, and are often found near streams or creeks. Specific locale data is not available.


History in the Hobby: Nicaraguan auratus were introduced into the US hobby in the 1990s. They have not been imported in nearly 20 years, and become more and more uncommon with each passing year.

Very beautiful bright green!!! Review by Bo
Ordered and received 3 healthy and active “Nicaraguan Green and Black” Auratus. Arrived quick and early in the day. Packed very well with the feeders I included with my purchase. Turned loose in their new home and they explored a bit then disappeared. I am now waiting on them become comfortable and show themselves. They are very brightly colored. Love them!

great frogs Review by Jeff
These guys were a bit shy at first but after they got settled in we see them out and active much more. Beautiful color, they are my kids favorite. (Posted on 5/16/2016)
Absolutely Gorgeous! Review by Tanya
I have had my 4 Nicaraguan babies for a week now and couldn't be happier. I waited a long time to get my dart frogs and I wouldn't shop anywhere else but joshs frogs to get them. The frogs are beautiful, healthy and their color is so vibrant. At first two of the frogs hid for the first three days but they are all out now exploring the whole tank and they really seem to like the water area. I'm so excited thanks Joshs Frogs for making me and my first frogs an great experience. (Posted on 11/30/2015)
Very healthy, active, and ravenous little buggers! Review by Tyler
So I ordered three of them and they arrived happy and healthy! Their very vibrant green contrasts very nicely with their dark black splotches. They are a little shy, even though their terrarium is full of hiding places. They really, really, REALLY love to sit in their broms. They cannot get enough fruitflies, either. They are eating machines.

On an off note, they are very proficient hunters and snag any remaining fungus gnats out of midair. Quite fun to watch (Posted on 11/2/2015)

Little dare devil! Review by Jenn
I bought one of these little guys a few months ago and he/she is just awesome. I have a rather large planted viv and its a good 3 1/2 feet tall, this little guy loves to climb the glass, all the way to the top then hop around from plant to plant until hes back to the bottom. Very active, well shipped, its as if he's lived here his whole life, settled right in. i couldnt be happier! (Posted on 8/18/2014)

Wonderful little guys (or gals)! Review by Scott
I ordered 4, they arrived this morning. They are all very active and could not wait to get out of the shipping cup to explore. Even though they are brand new to the tank only 1 of them hid the rest went out and about. Shipping was done very well and by their reaction not very stressful. Beautiful frogs worth every penny!
