Phelsuma klemmeri, also known as the Neon Day Gecko, Klemmer’s Gecko or in some cases Yellow-Headed Day Gecko (not to be confused with the Yellow-Headed Gecko), is a previously uncommonly-kept species that has risen in popularity over the last few years. An increasing number of hobbyists are being drawn to the little gecko’s strikingly bright appearance, an electric green-yellow head, nearly fluorescent turquoise body, and bold black markings, and their big personalities.
Despite their tiny size (a maximum of about four inches in length), this species is surprisingly bold and inquisitive, often basking in plain sight. In many cases, they will curiously climb onto a hand. Still, when startled, they can move with incredible speed and therefore it is recommended that handling be done in an enclosed area.
Housing & Cohabitation
A 12x12x18” size enclosure will comfortably house a pair and an 18x18x24” enclosure would house a small colony. These geckos are social to some extent, often communicating through head bobs and tilts, and will often bask together, though some individuals of either sex can be more dominant than others and can display aggressive behaviors. The adults are generally peaceful toward the offspring.
Phelsuma klemmeri are native to bamboo forests in northwest Madagascar and are endangered in the wild. When housed in captivity, this species thrives when provided with hollowed-out bamboo tubes placed at an angle in which to hide and lay eggs.
Heat, Light & Humidity
These Phelsuma are a diurnal, tropical species and require high humidity, UVB, and basking temperatures to thrive. Humidity should be kept between 60-80%, though they will tolerate occasional fluctuations. The enclosure should be misted two to three times per day to maintain these levels. A 5.0 or 10.0 UVB will ensure that Phelsuma klemmeri maintain their vivid coloration. Temperatures should range from 75 to 80 degrees, with a basking spot of 90-94 degrees Fahrenheit provided.
Diet
Due to their diminutive size, Phelsuma klemmeri require small, live insect prey, such as hydei or melanogaster fruit flies, pinhead to ⅛ size crickets, and tiny mealworms. Insects should be dusted in a vitamin and calcium supplement. In addition to live insects, this species should be fed a complete powdered diet, such as Pangea, ZooMed, or Repashy.
Breeding
Thankfully, Phelsuma klemmeri are not difficult to breed when given the correct environment. Bamboo or plastic test tubes are necessary for the females to deposit the eggs into, as this species does not glue its eggs. The eggs can be incubated inside the enclosure or carefully removed and incubated at 80-85 degrees. Typically, the female will lay two eggs per clutch, approximately 30 days apart, but single eggs are not uncommon. Any infertile eggs the female may consume for the calcium. The eggs will usually hatch between 30 and 60 days, but may take up to 90 days at lower incubation temperatures.
Availability
While previously obscure in the hobby, this species has become more widespread in captivity thanks to captive breeding efforts by dedicated hobbyists. Nearly, if not all, specimens are captive-bred, resulting in a hardier and more readily-available supply. While still relatively uncommon, captive Phelsuma klemmeri are increasing in numbers and popularity.
Overall, Phelsuma klemmeri are a stunning and personable species of gecko. Because of their bold, active, and social nature, they are fascinating to observe during the day and they will readily interact with their environment, each other, and their keeper. They are a splendid addition to a display vivarium or any reptile collection.
