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

Hello, Frank Indiviglio here.  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.

 

The tiny, highly-active Poison Frogs (Dendrobates spp.) and Mantellas do best in terrariums stocked with live mosses, ferns and other plants.  “Smart Plants” artificial bromeliads, which are equipped with tiny “ponds” in which frogs can deposit their eggs or tadpoles, are very useful (please see photo).

An easily-cleaned, bare-bottomed tank, tilted on one side to create a water section, is ideal for African Bullfrogs, Horned Frogs and other giants that require frequent water changes and are untroubled by a lack of “decorations”.

An aquarium half-filled with water and provisioned with a turtle basking platform and a submersible filter will suit Fire-Bellied Toads, American Green Frogs and other semi-aquatic species.

t95860African Clawed Frogs, Dwarf Clawed Frogs and Surinam Toads do not need a land area, but do best in tanks stocked with live or plastic plants upon which they can rest.

Terrariums for Marine Toads, American Toads, Smoky Jungle Frogs and other terrestrial species should have large land areas and a water bowl.  While many individuals will accept commercial caves and hiding spots, most prefer to dig into the substrate when seeking security.

“Hi-style” aquariums with sturdy live or artificial plants, driftwood, vines and branches make ideal homes for White’s Treefrogs, Asian Flying Frogs and similar arboreal species.

Substrate

Sphagnum and carpet moss works well for Poison Frogs and other forest-dwellers, while bare-bottomed terrariums are usually best for African Bullfrogs.

Smooth-Sided Toads, Oak Toads and others with similar lifestyles should be supplied with a mix of potting soil and coconut husk, or a substrate designed for burrowing amphibians.

Frogs often swallow substrate with their meals, and may incur intestinal blockages.  In general, gravel should be avoided; if used at all, select a size that is too large to be swallowed.  Take care with this…I’ve witnessed autopsies at the Bronx Zoo during which amazingly large stones were removed from frogs’ stomachs.  River rock (large black stones sold in garden supply stores) may be a useful option.

Light

Frogs and toads seem not to require UVB radiation, although there is some evidence that low levels may benefit Poison Frogs, Mantellas, and perhaps others that are active by day, dusk, and dawn.   For these, the Zoo Med 2.0 UVB Bulb is ideal.  UVA radiation may help to encourage natural behaviors and activity cycles.  Be sure to provide places where your frogs can avoid direct light.

Heat

Temperatures for tropical species should range from 75-82 F.  Frogs from temperate regions fare best at 65-74 F.  A cool retreat must always be available.  Some fine-tuning is often necessary in this critical area….please post below for detailed information.

A fluorescent bulb may provide enough heat – if not, try a small incandescent bulb or a ceramic heater; all can dry out the substrate, so monitor conditions carefully.

Humidity

Humidity needs vary, but even Colorado River Toads and other desert-dwellers require daily misting, and all should have access to an easily-exited water bowl.

Small humidifiers and humidity gauges specifically designed for use with amphibians and reptiles are very useful, especially for delicate species kept in dry regions.

Water Quality

Porous skins allow frogs and toads to absorb ammonia (released with their waste products) and other harmful chemicals.  Ammonia is extremely lethal; an aquarium test kit should be used to monitor its levels. 

Most aquatic species are best kept at a pH of 6.5 to 7.5; a simple test kit should be on hand.

Chlorine and chloramine must be removed from water used in aquariums, misting bottles and water bowls.  Liquid preparations that render water instantly safe should always be used.

An Important Note on Feeding

A highly-varied diet is essential.  Crickets alone, even if powdered with supplements, are not an adequate diet for any species.  Please see this article, and those linked below, for further information on this important topic. 

Please check out my posts on Twitter and Facebook.   Each day, I highlight breaking research, conservation news and interesting stories concerning just about every type of animal imaginable.  I look forward to hearing about your interests and experiences as well, and will use them in articles when possible.

Please also post your questions and comments below…I’ll be sure to respond quickly. 

 

Thanks, until next time,

Frank Indiviglio

Being born with a deep interest in animals might seem unfortunate for a native Bronxite , but my family encouraged my interest and the menagerie that sprung from it. Jobs with pet stores and importers had me caring for a fantastic assortment of reptiles and amphibians. After a detour as a lawyer, I was hired as a Bronx Zoo animal keeper and was soon caring for gharials, goliath frogs, king cobras and everything in-between. Research has taken me in pursuit of anacondas, Orinoco crocodiles and other animals in locales ranging from Venezuela’s llanos to Tortuguero’s beaches. Now, after 20+ years with the Bronx Zoo, I am a consultant for several zoos and museums. I have spent time in Japan, and often exchange ideas with zoologists there. I have written books on salamanders, geckos and other “herps”, discussed reptile-keeping on television and presented papers at conferences. A Master’s Degree in biology has led to teaching opportunities. My work puts me in contact with thousands of hobbyists keeping an array of pets. Without fail, I have learned much from them and hope, dear readers, that you will be generous in sharing your thoughts on this blog and web site. For a complete biography of my experience click here.
