Name:

Caribena versicolor: The name translates to “Caribena” Caribbean and “versicolor” changeable in color. Thus, it is the Caribbean color changing tarantula. This name is probably a reference to the variety of coloration found over its body ranging from blue greens to purple. The common name references the island chain from which the species originates and the pink pads of its terminal tarsi. The species was originally categorized in the genus Aviculara.  

• Original species description was based on a male and female from two different species, causing future taxonomic confusion
• Able to jump up to 30cm
• Regarded as one of the most beautiful tarantulas in the hobby

Recommended Enclosure Size:

Antilles pink toes can be kept in a 12”x12”x18” side opening terrarium like the Exo Terra mini-tall terrarium, as species in this genus tend to build their nests toward the top of the terrarium. They are arboreal, so they will also benefit from a variety of terrarium furniture as well to climb on. 4-5” of substrate will help the terrarium retain humidity while still allowing for this species high ventilation requirements. This spider’s native habitat is highly stable in temperature and humidity and so has corresponding environmental requirements. A low powered heating pad with thermostat to establish a heat gradient s necessary. The spider will situate itself in whatever part of the heat gradient it finds comfortable.

Temperature:

78-82°F

Humidity:

75-80% humidity

Size:

At least ½”. Grows up to 5-6” in females, males are somewhat smaller

Age:

2-3 years in males, 8-12 years in females

Feeding:

Drosophila melanogaster. As it grows, so should its prey. Prey items should be no larger than the size of the spider’s abdomen. Remove uneaten prey items: these may endanger the spider during molting. Spiderlings can be fed as frequently as they are willing to eat but should be fed at least twice a week otherwise. You can find producing D. melanogaster colonies here.

Sexing:  

To identify a male or female before it has reached sexual maturity, you will need to examine its cast skin which in females will have a folded area in the abdominal region and will eventually connect to her spermatheca when she is mature. Alternatively, when sexually mature, the spiders may be sexed based on the proportion of their abdomen to the rest of their body. The male’s abdomen will be smaller than its cephalothorax while the female’s will be about the same size or slightly larger. This method is much easier than using a cast skin as this species is very small and identifying the characters previously described will probably require a microscope. Due to their age, Antilles Pink Toe Tarantulas sold by Josh's Frogs are sold as unsexed animals.

Color/Pattern:

The Antilles Pink Toe tarantula is rightly regarded as gorgeous with a metallic blue green sheen to its carapace (most clear on its cephalothorax which is devoid of hair) and pink to purple hairs covering its abdomen and legs. These hairs are quite long, giving the tarantula a fluffy appearance. The hairs are urticating, however, so we advise resisting the urge to pet it.

Social Behavior:

This tarantula should be kept singly.

Breeding:

When breeding Antilles pink toes, it is best to plan it for about one month after the female molts. If a molt follows the pairing before eggs can be laid, the reproductive material contributed by the male will be discarded in the process. The female should also be well fed prior to the pairing. If successful, the female will eventually construct an egg sac, which should be removed about four weeks after for incubation.

Natural Range:

Martinique
