About This Product

 Defining characterisitics:

  • Diurnal
  • Quick and active
  • Easy to keep
  • Larger Sphaerodactylus micro gecko, but still tiny
  • Small size = less expensive setup

Name: Sphaerodactylus dimorphicus. Not official, but we’ve elected the common name yellow-tailed gecko for the yellow tail common to juveniles, females, and males in this species.

Recommended Enclosure Size: Adults should be kept alone or in pairs in a 8x8x12 glass enclosure or 12x12x12 enclosure. Because this species does not grow very large, upgrading adults to a larger enclosure is usually unnecessary. Coco fiber-based substrates or sand-soil substrates work well. A bioactive substrate can be made with BioBedding, springtails, and isopods. Keep substrate moist. A layer of leaf litter should be added on top of the substrate. Hides should be provided; cork and similar items work well. Climbing materials like rocks, driftwood, cork bark, and manzanita branches can be provided. Live plants are also a welcome addition.

Temperature: Keep yellow-tailed geckos between 75-80 F. A heat source is not required if stable temperatures are maintained. If a heat source is provided, use a low wattage heat pad or bulb to prevent overheating.Temperature should be monitored with a digital thermometer. Night temperatures should not fall below 65 F. UV light requirement debated; if used, provide plenty of shade in enclosure.

Humidity: Yellow-tailed geckos need a humid but well-ventilated setup between 60-70%. Plants can be added to provide humid microclimates. Ambient humidity should be monitored with a digital hygrometer. Yellow-tailed geckos should be lightly misted daily or every other day provide dew on enclosure walls and cage items from which they can drink, but enough ventilation should be provided to allow the enclosure to dry out after several hours. A shallow water dish can be provided but is not necessary with regular misting.

Size: One of the larger Sphaerodactylus mico geckos, but still very small. Hatchlings are a little over an inch, and adults will only reach 2.6-2.8 inches!

Age: Yellow-tailed geckos are at least 4 weeks old when sold by Josh’s Frogs. It is estimated that these geckos live for 10-20 years in captivity.

Feeding: Yellow-tailed geckos sold by Josh’s Frogs are fed pinhead crickets and ⅛-inch crickets. These juveniles can also be occasionally offered extra small black soldier fly larvae, melanogaster fruit flies, and springtails. Adults should be fed a staple of  ⅛-inch crickets, but can also be offered black soldier fly larvae, melanogaster and hydei fruit flies, dwarf white isopods, and bean beetles. All feeder insects should be gutloaded and dusted with vitamin/mineral supplements, and can be offered in a food dish.

Sexing: Yellow-tailed geckos are sexually dimorphic and can be visually sexed. Whereas females mostly resemble juveniles in color and pattern, males become adorned with stark spotting on their head, which continues faded down the rest of their body.

Color/Pattern: Juveniles and females have a yellow tail and gray-blue body, all patternless. Males are similar in color, but are adorned with well-defined spots on their head that continue, faded, down their body.

Social Behavior: This species is best kept alone or in a single pair.

Breeding: A light brumation period in the winter or longer days in the summer will help incite breeding. Females lay single eggs every 3 weeks in a secure area, and will often make use of strategically placed egg-laying tubes. Eggs hatch within 60-80 days.

Natural Range: Yellow-tailed geckos are found in the province of Santiago in Cuba.

History in the Hobby: Despite being not too difficult to keep and breed, captive bred individuals are not often readily available. We’re excited to make this micro gecko more popular and available!

Cute Mini Gecko

I imagine behavior would vary based on setup, so here is some info on my vivarium: I have a single gecko in an Exoterra Nano Tall with 3 sides covered in 3D background, some ghost wood branches and a heavy planting of mosses, sellaginellas, young terrestrial ferns and tiny epiphytic ferns. I have seedpods and leaf litter on 75% of the bottom of the vivarium, with an overhang sheltering the area. It seems like enough space for my single gecko, but I'd be worried about putting two in there. Like clockwork, my gecko comes out in the evening at 8, and stays out hunting until lights out at 10. This is supposedly a diurnal genus, but my gecko seems more crepuscular, though maybe my behavior is influencing them. They hunt all over the vivarium, but don't seem to like the leaf litter too much, preferring the planted areas. They seem to be worried about climbing on the glass itself, but sit on the screen roof pretty often. Over all, they are much more outgoing than I expected from the available information about this species, though still rather shy.

Wonderful micro geckos

These have to be one of the most interesting dwarf or micro geckos in herpetoculture. The males and females are easily sexed as adults as they show sexual dimorphism with the male having a gray head with rounded brown or black spots and the females having a pale-yellow head hence the name "dimorphicus". They tend to be very active in the vivarium and are not afraid to be approached. The one's I received were immature which made acclimation in my vivarium habitat all the better. These geckos seem to enjoy feeding on adult Fungus Gnats that hatch in the vivarium and often jump from the vivarium floor into the air to try and capture them. Thanks Josh's Frogs from making these unique micro geckos available!
