Female mossy frogs (Theloderma corticale) are one of the most elusive and sought-after amphibians in the UK exotic pet scene. Known for their incredible camouflage and docile temperament, these Vietnamese natives are increasingly popular with collectors and breeders alike. But finding a female mossy frog in the UK can be a real challenge. That’s why enthusiasts turn to trusted sources like Frogfather.co.uk — a reputable supplier of captive-bred mossy frogs with a focus on healthy, well-sexed specimens.
In this guide, we’ll cover everything you need to know before buying a female mossy frog in the UK: how to care for them, where they come from, tips for breeding them in captivity, how to tell males and females apart, and the surprising science behind why female mossy frogs are so rare.
Natural Habitat and Origin of Mossy Frogs
Native to the limestone caves and wet forested regions of northern Vietnam, mossy frogs thrive in cool, humid environments with plenty of vertical structure and shallow water sources. In the wild, they hide among moss-covered rocks and bark, which they mimic perfectly thanks to their textured green and black skin. These frogs are semi-aquatic and primarily nocturnal, often seen clinging to vertical surfaces in humid cave entrances or under forest canopies.
Their natural environment is typically 18–24°C with high humidity (80–100%) and consistent access to fresh water. Understanding these wild conditions helps us create an ideal captive setup.
Mossy Frog Care in Captivity
Enclosure Setup
A glass vivarium with excellent ventilation and high humidity is essential. We recommend a vertically oriented tank of at least 45x45x60 cm for an adult pair or trio. Key features should include:
- Background with cork bark or foam covered in live moss
- Plenty of climbing structures (branches, rocks, vines)
- Shallow water area for soaking
- Misting system or daily manual misting to maintain 90–100% humidity
- Temperatures between 18–24°C; avoid overheating
Substrate and Décor
Use a moisture-retaining substrate like ABG mix, sphagnum moss, or coco coir. Include leaf litter and live plants such as pothos, philodendrons, or bromeliads to stabilise humidity and create natural hiding spots.
Feeding
Mossy frogs are insectivores and do well on a varied diet of:
- Crickets (gut-loaded)
- Dubia roaches
- Waxworms (occasional treat)
- Springtails and isopods (bonus bioactive cleanup crew)
Dust food with calcium and multivitamin supplements 2–3 times per week.
Breeding Mossy Frogs in Captivity
Captive breeding of Theloderma corticale is rewarding but requires patience and careful planning. A rain chamber or controlled misting to simulate seasonal rainfall is often necessary to trigger breeding.
Breeding Setup
- Increase misting to simulate a rainy season
- Add a large water dish or breeding pool
- Maintain consistent temperatures of around 22°C
- Reduce disturbance and lighting during the night
Courtship and Egg-Laying
Males will call softly to attract females. Eggs are typically laid above the water line on mossy or smooth vertical surfaces. After hatching, tadpoles drop into water and begin development.
How to Sex Mossy Frogs: Male vs Female
Sexing mossy frogs can be tricky until they reach maturity. Here are some common differences:
Males:
- Smaller and more slender
- Call at night (soft, clicking calls)
- Darker throat area (vocal sac)
Females:
- Larger and rounder body shape
- No vocal sac or call
- More robust hind legs
Visual sexing can be unreliable in young frogs, which is why reputable breeders like Frogfather.co.uk offer sexed or semi-sexed animals when possible.
Why Are Female Mossy Frogs So Rare?
In captivity, the ratio of male to female mossy frogs can be skewed — sometimes heavily — in favour of males. Several theories exist:
- Temperature-dependent sex determination (TSD): While not confirmed for mossy frogs, many amphibians exhibit TSD, where incubation temperature influences the sex of the tadpole. If the temperature range during development favours male expression, more males are produced.
- Hormonal balance: The presence of certain hormones in water or food may influence gender development.
- Inbreeding and founder effects: If initial captive populations were male-heavy, the trend may persist genetically.
Until more research is done, female mossy frogs will likely remain the rarer sex in hobbyist circles.
Where to Buy Female Mossy Frogs in the UK
Finding a well-established, healthy female mossy frog in the UK requires patience and care. Look for breeders and suppliers that:
- Offer captive-bred (CB) specimens, not wild-caught
- Provide accurate sexing and husbandry information
- Have transparent customer reviews
At Frogfather.co.uk, we occasionally offer female mossy frogs and guaranteed pairs when available. Stock is limited, so check back frequently or contact us directly for availability.
Final Thoughts
