About This Product

Defining Characteristics:

  • Ephebopus cyanognathus have a fast growth rate.
  • It is actually the chelicerae (or fang housings) that are electric blue - not the fangs themselves!
  • This is a smaller species, only getting between 2 and three inches
  • They are a newer species, only having been discovered in 2000. It has been popular ever since.

Name: Ephebopus cyanognathusis also commonly known as “Blue Fang Skeleton Tarantula” or just “Blue Fang Tarantula”.

Recommended Enclosure Size & SetupEphebopus cyanognathus is a terrestrial species with some burrowing tendencies. Surface area of the enclosure should be no less than two times the spider's diagonal leg span in one direction and three times the diagonal leg span in the other.

The enclosure should be tall enough to accommodate 2-3 inches of substrate for slings and 4+ inches for adults. ABG mix, coco cradle, or Dig-It are all good substrate options for this species, but our Pet Bug Team prefers ABG all the way!

We recommend against allowing your terrestrial spider more than two times their diagonal leg span for head space above their substrate as a fall from any higher could result in serious injury.

Temperature (°F): This species thrives in the mid 70s to low 80s, so a temperature of 75 degrees is ideal. Temperatures regularly dipping below 65 degrees or spiking above 85 degrees should be avoided.

Humidity: These spiders thrive in a humid environment, so the recommended ambient humidity should stay between 70% and 80%. This can be achieved by making sure the substrate is always slightly moistened. Depending on your location, you may need tools such as a humidifier to achieve this environment. A hygrometer is a great way to monitor the humidity for your animal and see if you need to make any adjustments to your husbandry.

The enclosure sides and decor should be spritzed lightly around 2 times a week to provide your spiderling droplets to drink from, but do not spray your spider directly.

Size: At the time of sale, this animal will be at least ¼ inch . Females can grow to be up to 3 inches, and typically the males are a bit smaller.

We use diagonal leg span to measure our spiders.

Age: Before making this species available to our customers, we ensure that they are well-established. This means our spiders are generally molted to a minimum of third instar and will have hatched two to three months prior to being listed for sale.

For spiders that we have not produced in house, we like to get two to three solid feedings in as well as the aforementioned minimums. They go through a 2 week minimum quarantine process to ensure the health of the animal.

For this species, the average lifespan is 3-4 years in males, and 15 years in females when provided an adequate environment.

Feeding: At the time of sale, this animal is eating hydei fruit flies once a week. Prey items should be no larger than the size of the spider’s abdomen, and grow in size as the animal does. 

Remove uneaten prey items after 24 hours as these may stress your animal out or endanger the spider during molting.

Never attempt to feed a freshly molted tarantula less than a week after their molt to prevent injury to the spider. Depending on the spider's age, the hardening process could take 48 hours to 1 week.

Sexing: Due to their age, Ephebopus cyanognathusis sold by Josh’s Frogs are unsexed.

Coloration/Patterning: As spiderlings, Ephebopus cyanognathusis have a metallic green abdomen, metallic blue chelicerae, bright orange/pink legs and a black carapace, making them an eye-catcher for anyone who sees them. As they mature, they become brown across their entire body, while continuing to keep the stunning blue chelicerae. 

Social Behavior: Ephebopus cyanognathusis is not a sociable animal and should be housed as an individual. Attempts at cohabitation will likely result in cannibalism.

Natural Range: Ephebopus cyanognathus are native to French Guiana.
