Ocellated Gecko
Sphaerodactylus argus
A microscopic Caribbean gecko that thrives in dense, damp leaf litter. It requires a heavily planted nano-terrarium with constant 70-85% humidity, a moderate thermal gradient, and extremely tiny prey to prevent dehydration and starvation.

Species description
Geographical Origin and Habitat: Native to the Caribbean (primarily Jamaica and Cuba) and introduced to the Florida Keys. It inhabits coastal forest undergrowth, suburban gardens, and coconut groves, sheltering in damp leaf litter. They prefer microhabitats with high relative humidity and plenty of organic ground cover. They can often be found in agricultural fields and plantations.
Taxonomy and Genetics: Family Sphaerodactylidae, genus Sphaerodactylus. Genetically adapted to high-humidity tropical microclimates within island ecosystems. The species name argus refers to the mythical hundred-eyed giant, due to the ocelli pattern. They belong to the family Sphaerodactylidae.
Behavior and Habits: Primarily crepuscular or diurnal. Active foragers within leaf litter, hunting micro-arthropods. Extremely fast and secretive, avoiding open spaces and preferring ground-level habitats. They are very cryptic, spending most of their time hidden under bark or leaf litter. They hunt actively during dawn and dusk hours.
Morphology: Tiny adult size of only 4 to 5 cm (1.5 to 2 inches). Features a pointed snout and distinctive white spots (ocelli) bordered in black on the head and neck. Dark brown base body color. They have specialized toe pads that allow them to climb smooth surfaces like glass easily. Unlike larger geckos, their skin is scale-like and dry.
Care, breeding and tankmates
Terrarium Setup: A nano-terrarium (e.g., 12x12x12 inches / 30x30x30 cm) is ideal. Use a moisture-retaining soil-sphagnum substrate topped with a thick layer of leaf litter and small cork bark slabs. Ensure all ventilation meshes have opening sizes small enough to prevent the geckos from escaping. A glass terrarium with sliding front doors is best.
Lighting and Heating: Keep temperatures moderate: ambient at 24-26°C (75-79°F) and a warm zone of 28°C (82°F). Night drop to 20-22°C (68-72°F). Low-intensity UVB (2-5%) should be provided. Use low-wattage heating elements to prevent rapid dry-out of the microterrarium. A daytime temperature of 26-28°C (79-82°F) is ideal.
Humidity and Hydration: Constant high humidity of 70-85% is critical. Mist the enclosure once or twice daily to provide drinking water droplets and prevent dry conditions. Mist the enclosure once or twice daily, focusing on the live plants to create drinking spots. Live mosses are excellent for keeping humidity high.
Feeding and Supplementation: Feed micro-insects such as springtails, dwarf isopods, and flightless fruit flies. Dust all food items with a calcium and Vitamin D3 supplement twice a week. Dust all prey items with high-quality calcium and multivitamin powders. Offer pinhead crickets, fruit flies, and small bean beetles.
Compatibility: Can be housed as a single specimen or a male-female pair. Never house multiple males together. Do not handle, as they are fragile and fast. Do not house multiple males together, as they will fight over mating rights. Provide visual barriers to help submissive females hide.
Health and Common Diseases: Dehydration is the primary cause of death. Metabolic Bone Disease (MBD) can occur from poor supplementation. Incomplete shedding on the toes can occur if dry. Due to their size, treating sick individuals is difficult, making prevention the best approach. Avoid sudden drops in humidity.

The catalog's scalar value is 3.3 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 3.3 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
