Pygmy chameleons are a captivating group of small, terrestrial reptiles prized for their gentle personalities, fascinating camouflage, and relatively compact care requirements. This comprehensive care sheet covers husbandry for all prominent species available in the pet trade, including Rieppeleon brevicaudatus (Bearded Pygmy Chameleon), Rhampholeon temporalis (Usambara Pitted Pygmy Chameleon), Rhampholeon spectrum (Spectral Pygmy Chameleon), and a brief mention of rarer species within this genus. Each section is meticulously detailed to help keepers create optimal, species-appropriate environments for healthy, thriving pygmy chameleons.
Overview of Pygmy Chameleon Species
- Rieppeleon brevicaudatus (Bearded Pygmy): Native to the Eastern Usambara and Uluguru Mountains in Tanzania, this is the most popular species in captivity. Adults grow to 3–3.5 inches (8–9 cm) and possess the characteristic “beard” of scales under their chin. They display earthy hues—brown, yellow, green, and mottled patterns—mimicking wilted leaves for camouflage.
- Rhampholeon temporalis (Usambara Pitted Pygmy): Endemic to humid mountain forests, particularly the Usambara region of Tanzania. They show muted brown or gray coloring, sometimes marked with subtle stripes and have noticeably longer tails than brevicaudatus.
- Rhampholeon spectrum (Spectral Pygmy): Found from Cameroon to the Congo, this species showcases mottled browns, grays, and red tones, with a soft nasal “horn.” Their tails are also longer, and males can be identified by a hemipenal bulge.
- Other species: The genus Rhampholeon contains over 26 recognized species, many unique to isolated mountain forests across East and Central Africa, with ongoing discoveries and research into their diversity and conservation.
Terrarium Setup
Enclosure
- Size: A single pygmy chameleon requires at least a 5-gallon glass aquarium, with each additional animal needing another 5 gallons. Popular choices include 10- to 20-gallon horizontal tanks for groups (never house more than one male per enclosure to avoid aggression).
- Substrate: Provide a 2–3 inch layer of moisture-retentive substrate such as coconut fiber, organic soil, or specialized reptile mixes. A top layer of clean, chemical-free leaf litter is essential for natural behavior and humidity retention.
- Décor: Dense live or artificial plants, thin branches, sticks, and vines are mandatory. Hiding spots and varied cover reduce stress—a bare terrarium leads to chronic stress and illness. Avoid vertical set-ups: pygmy chameleons are terrestrial and utilize floor space more than vertical climbing.
Microclimate
- Temperature: Maintain 60–78°F (15–25°C). Never exceed 80°F (26°C)—higher temperatures can quickly become fatal. Night drops are beneficial; aim for a 10-degree reduction at night.f
- Humidity: Relative humidity should remain between 60 to 80%. Achieve this by hand-misting the enclosure at least twice daily, using a fine sprayer or programmable mist system. Allow the habitat to dry between mistings. Live plants help stabilize humidity; optionally add a cool-mist humidifier if needed.
Lighting and Heating
- Lighting: A low-output UVB fluorescent (2.0 or used 5.0) is recommended, simulated for 12 hours daily. While debate exists over the necessity of UVB for pygmy chameleons, it benefits both plants and possibly helps the animals synthesize vitamin D3.
- Heating: Ambient home temperatures are typically sufficient. Avoid basking bulbs unless your room remains unusually cool; if a basking spot is provided, ensure it does not exceed 78–80°F (25–26°C), and always offer shaded retreats in the landscape to let chameleons thermoregulate themselves.
Hydration and Water
- Misting: Pygmies will not recognize standing water—provide hydration by misting the foliage and decor. They drink droplets from leaves and litter. A drip system is unnecessary and could contribute to overwatering.
- Water Quality: Dechlorinated or filtered tap water is generally safe. If your water source is hard or chemically treated, consider additional filtration to prevent mineral buildup or toxicity.
Diet and Nutrition
- Staple foods:
- Appropriately-sized crickets (1/8-1/4 inch)
- Flightless fruit flies
- Baby silkworms/hornworms
- House flies, small roach nymphs, and mantid nymphs (as supplement, not staple)
- Feeding frequency:
- Hatchlings/juveniles: Feed daily with as many small prey items as they’ll eat in a session
- Adults: Feed 4–6 small insects every other day
- Gut-loading: Always gut-load insects with calcium-rich vegetables and a quality commercial gut-load product 24 hours before feeding.
- Supplements: Lightly dust insects with calcium (no D3) twice weekly, add a multivitamin once monthly, and calcium with D3 once monthly. Avoid over-supplementation, as metabolic requirements in montane species are lower. Neonates require more supplementation; specifics are provided in the referenced care documentation.
- Treats: Waxworms, butterworms, and wild-caught insects may be offered occasionally. Never use mealworms; they are poorly digested and nutritionally unsuitable.
Social Behavior and Temperament
- Handling: Pygmy chameleons are best as a “look, don’t touch” pet. Their delicate size and secretive nature make them susceptible to stress when handled.
- Cohabitation: Multiple females or one male with several females can live together in sizable, densely-planted setups. Never house two males together without extensive space and careful monitoring—dominance displays and even physical altercations are possible.
- Lifespan: Pygmy chameleons live 1-3 years in captivity, with most wild-caught individuals living toward the lower end of this range due to stress and parasite load.
Breeding, Egg-laying, and Hatchling Care
- Breeding group: Pygmy chameleons may breed spontaneously when housed with both sexes. Females become noticeably more robust when gravid but rarely display distinct behaviors or coloration changes.
- Egg laying: Females lay 1–12 eggs at a time, burying them in the moist substrate. Provide substrate with varying moisture so that females can choose their preferred spot.
- Incubation: Remove eggs if discovered and incubate at 65–78°F (18–25°C) in a sealed container with moist vermiculite. Hatching occurs in 45–90 days.
- Hatchlings: Separate neonates from adults. Hatchlings should be kept in smaller enclosures (bare-bottomed) with ample plant cover, misted several times daily, and fed as many flightless fruit flies as they can eat.
Health, Hygiene, and Maintenance
- Parasites: Most wild-caught pygmy chameleons arrive with internal parasites. Quarantine, routine fecal examinations, and veterinary guidance are strongly advised. Never house captive-bred and wild-caught animals together.
- Shedding: Pygmy chameleons shed infrequently, usually in one or two large pieces; this is natural. Low humidity can cause retention, so monitor conditions closely.
- Cleaning: Spot clean every few days, remove shed skin and uneaten insects, and replace all substrate every 3–4 months. Sanitize décor with reptile-safe cleaner between substrate changes.

Troubleshooting and Frequently Asked Questions
- Why does my pygmy chameleon appear dull or inactive?
- Stress, inappropriate temperatures, or humidity are common causes. Confirm terrarium conditions and minimize handling.
- Do they need live plants?
- Live plants help stabilize humidity and provide vital cover, mimicking their natural habitat.
- Is UVB necessary?
- While controversial, a low-output UVB bulb is recommended to avoid deficiency and support naturalistic enrichment.
Species Conservation Note
Many wild-caught pygmy chameleons originate from threatened habitats, such as the isolated forests of Tanzania’s Eastern Arc Mountains. Responsible keepers should prioritize captive-bred animals whenever possible and support habitat conservation efforts.
