Name: Ranitomeya ventrimaculata 'Arena Blanca'. Formerly known as Dendrobates ventrimaculatus, this frog is commonly known as the Amazonian Poison Dart Frog, and simply as 'vents' in the hobby. Recent taxonomic revisions have labeled this species as Ranitomeya amazonica. The species name refers to it's spotted underside.

Recommended Vivarium Size: A 10 gallon aquarium is suitable for 2-3 Ranitomeya ventrimaculata, but Josh's Frogs recommends a 20H or 18x18x18 Vivarium for 1-3 frogs. Not sure how to set up a vivarium? Please watch our video on How to Set Up a Vivarium.

Temperature: They can tolerate a temperature range of 65 F to 80 F, but prefer temperatures in the low to mid 70s. Temperatures over 85F are dangerous.

Humidity: Like most poison dart frogs, Vents prefer a humidity range of 80 – 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.

Size: Adult female and male R. ventrimaculata 'Arena Blanca' are similar in length, measuring in at around an inch. All of the Ranitomeya ventrimaculata 'Arena Blanca' froglets Josh's Frogs sells are well started juveniles, and measure approximately 1/2” long.

Age: Ranitomeya ventrimaculata 'Arena Blanca' is capable of living well over 10 years in captivity under ideal conditions, although a lifespan of 5-8 years is more common. All vents for sale at Josh's Frogs are well started juveniles, and are 2-3 months old.

Feeding: Like most poison dart frogs, vents prefer smaller foods. All of the thumbnail dart frogs sold by Josh's Frogs will readily eat Drosophila melanogaster fruit flies. Adult Ranitomeya ventrimaculata 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: Ranitomeya ventrimaculata 'Arena Blanca' are fairly easy to sex as adults. Females are much wider than males, as they lay eggs on a weekly basis. 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: Arena Blanca vents are fairly consistent in color and pattern. Exhibiting a yellow, orange, or red and black striped body and blue-gray legs, they are a striking little thumbnaill dart frog! 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 5 gallons per frog. As they reach sexual maturity at 5-8 months of age, the social dynamic in a group of vents may change and females may eat each other's eggs, although most will even breed together in the same film canister! 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: Vents are one of the easiest poison dart frogs to breed. Best bred in groups, males call to attract a female to a suitable egg laying site. Then, 4-8 eggs are laid under water (often in a film canister or a bromeliad). The eggs hatch into tadpoles, which then take 60-80 days to complete metamorphosis into miniature versions of the adults. Tadpoles will feed on dead fruit flies, the standard frog and tadpole bites/sera micron fare, and even unfertilized eggs if left in with 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: Ranitomeya ventrimaculata is a lowland species, inhabiting the Amazonian Drainage Basin in Peru, near Iquitos.

History in the Hobby: Vents have long been a mainstay in the dart frog hobby, but this new morph is striking to behold! Brought into the US trade by Mark Pepper of Understory Enterprises, these frogs quickly spread across the hobby due to their bright colors and ease of breeding.

Love my Arena Blanca

I got 3 of these 2 weeks ago Couldn't be happier with them. They are not shy at all. They are all over the place and even come over to take a peek at me. I get a real kick out of the one, likes to climb the "tiny dancer plant" and sit one op of the highest leaf.
