Keeping Frogs and Toads as Pets – Creating a Terrarium and Best Amphibian Care Products

From tiny “living jewels” to hulking giants capable of consuming bats, snakes and rodents, the world’s nearly 6,000 frog species present an amazing array of pet-keeping opportunities.  With proper care, some may live for decades (to age 50 in the case of the African Bullfrog), and quite a few are active by day and quickly learn to accept food from one’s hand.  However, keeping frogs and toads as pets means providing a habitat that meets their specific needs – humidity, temperature, substrate, terrarium size and shape, light, water quality and other conditions must be carefully considered.

Although each has needs that vary from those of others, some general rules have emerged.  The following information is drawn from my experiences with hundreds of species over a lifetime of frog-keeping in zoos and at home.  It can be applied to most of those that you are likely to encounter.  However, details will vary – please post below for information concerning individual species.

Housing

Please remember that your frog’s natural history will dictate the type of terrarium it requires…please post below to discuss the need of individual species, or to share your observations.

Setting up the Terrarium

Active, sedentary, high-strung, aquatic, arboreal and terrestrial frogs and toads utilize their living spaces in different ways.  Following are some basic guidelines for popular species. Read More »

UVB Light: Why Do Reptiles Need It, and Which UVB Bulbs are Best?

Our understanding of the role that Ultraviolet B Light plays in the lives of reptiles and amphibians has increased greatly over the last few decades, but we still have much to learn about the needs of individual species. A good deal of conflicting information has been published, and opinions differ even among my well-experienced herpetologist colleagues. Today I’ll provide some basic information on UVB light in natural and captive situations, including some tips as to how best to provide it to the animals under your care. I’d like to stress that many variables will affect your individual situation…please post below for specific information.

What is Ultraviolet B (UVB) Light?

The various types of light are characterized by different wavelengths, which are expressed in nanometers (nm). There are three types of Ultraviolet Light, two of which are important to reptile and amphibian husbandry.

UVB Light has a wavelength of 280- 320 nm. Many reptiles synthesize Vitamin D3 (or, more specifically, Pre-Vitamin D/Cholecalciferol) in their skin when exposed to UVB light. The optimum range for Vitamin D3 synthesis in reptiles is 290-315 nm.

The Best Foods for Poison Frogs, Mantellas and Other Tiny Amphibians

I began working with Poison Frogs and Mantellas in zoos just as the secrets to longevity and breeding were being discovered.  Today, captive-bred animals are almost mainstream.  This is wonderful, but there is a downside – they are sometimes viewed as “simple to keep”.  But while these tiny gems can be surprisingly hardy, they will not thrive long-term if their unique nutritional requirements are not met.  Friends of mine who have broken new ground with Poison Frogs – in one case years before most zoos did – have always expended a great deal of effort on providing a varied diet.  The following information is drawn from their and my own experiences over several decades, and may also be applied to the care of many other small and newly-transformed amphibians.

General Considerations

Although we do not know the exact nutritional needs of any species, certain principles have become evident.  Chief among these is that a highly-varied diet is essential. Crickets alone, even if powdered with supplements, are not an adequate diet.  There are exceptions, but nearly every study of free-living amphibians reveals that a surprising range of prey species are consumed.

The Best Humidity Gauges for Reptile, Amphibian and Invert Habitats

Like most lifelong animal keepers, I consider myself to be a fairly good judge of humidity levels in the home terrariums and zoo exhibits under my care.  But when I began working in new buildings equipped with state-of-the-art hygrometers (humidity gauges), I quickly realized that I had much to learn.  I was especially surprised to discover how widely humidity levels can vary within even a small enclosure, and how this can affect every facet of an animal’s life.  The accurate, easy-to-use humidity gauges now available offer us the chance to provide better care to our charges and perhaps to uncover important new details about their lives.

Recent Innovations in Humidity Monitoring

Over the past several decades, hobbyists and zoos have greatly expanded the number of rare and delicate species that can be kept and bred in captivity.  Many of these successes have been due to an increased understanding of the roles that UVB, temperature, diet and other such factors play in their lives.

Humidity levels have also been taken into account by serious animal owners, but this topic has been given less attention than others.  This is partially because many reptiles, and some amphibians and invertebrates, can meet their needs by soaking in a water bowl or retreating to a moist shelter.  But the real obstacle has been the unavailability of affordable hygrometers designed for use with animals.  Happily, humidity gauges that fit just about every terrarium and budget are now available, and all are very simple to use (since I can do it!).

Day Gecko Care – Terrarium Set Up and the Best Supplies

Gaily clad in brilliant, neon-hued colors, Day Geckos (Phelsuma spp.) are among the most desirable of all lizard pets, so here is a short article about Day Gecko care.  Many are hardy, long-lived, and relatively simple to breed…but only if they are housed in a properly-designed habitat.  Active and alert, these cautious animals fare poorly in bare enclosures, but are ideally suited for life in naturalistic, planted terrariums.  The security provided by dense plantings and well-placed branches will put Day Geckos at ease and allow you to view a wide range of fascinating behaviors.

Setting up the Terrarium

Day Geckos are highly arboreal and must have climbing opportunities.  “High-style” aquariums make fine homes.  A pair or trio of Spotted, Yellow-Throated or other small species can be kept in a 15-20 gallon aquarium.  A 30-55 gallon tank will accommodate the same number of Standing’s, Madagascar or Giant Day Geckos.  Always opt for the largest terrarium possible.

Day Geckos need spacious enclosures that mimic their natural habitat.  Live plants such as Pothos and Philodendron will provide visual barriers between tank-mates and a sense of security.  Rolled cork bark and hollow bamboo sections make ideal hideaways and perching sites, and should be arranged both horizontally and vertically.

Be sure to establish plenty of basking sites near heat and UVB bulbs, as dominant individuals may exclude others from these important areas.

The terrarium’s screen lid must be tightly secured with clamps. Read More »
