That Reptile Blog – Reptile, Amphibian and Exotic Pet Care and Information

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!).

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 »

During a long career zoo career that found me working with animals ranging from ants to elephants, I’ve had many occasions to review veterinary and pathology reports.  In doing so, I’ve come to understand that zoonotic diseases – those that can pass from animals to people – are a potential concern in the keeping of any pet.  Most people associate Salmonella, the best known zoonotic, with reptiles, but nearly any animal, including dogs, cats and birds, may harbor this bacterium. Fortunately, Salmonella and other infections can be avoided by following a few relatively simple rules.

Note: This article is not meant to replace a doctor’s advice, nor is it intended to discourage pet ownership.  By observing a few simple precautions, the most commonly-encountered problems can be effectively managed.  Please post your questions and concerns below, and be sure to consult your doctor or veterinarian for specific information concerning disease prevention and treatment.

Tempted to buy that tiny green turtle being offered for a mere dollar or two?  While Red-Eared Sliders (Trachemys scripta elegans) can make an interesting and responsive pets, their care is far more complicated (and expensive!) than most new owners expect.  In perhaps no other animal is the distinction between initial price and long term cost of care so great.  Furthermore, the care guidelines offered by many sellers are often overly-simplified and inaccurate.  Following is a list of everything you’ll need to provide a proper home for Red Eared Sliders and other species with similar lifestyles (i.e. Map, Painted and Side-Necked Turtles, Cooters), along with notes concerning each item.  An in-depth article about Slider care and natural history is posted here.

Do Not Buy Hatchlings!

Although newly-hatched Sliders are still offered for sale, usually at fairs, carnivals and street stalls, it is illegal to sell them (or any turtle less than 4 inches in length) in the USA, and has been since 1975.  The law was enacted by the Food and Drug Administration in response to Salmonella outbreaks linked to hatchlings. For further information on the Salmonella- turtle connection, please see this article.

Because Sliders grow much faster than most owners expect, turtle rescue organizations are swamped with unwanted pets.  Please consider adopting rather than purchasing a turtle; please post below if you need adoption assistance.  Read More »

The 8-14 inch-long Collared Lizard, Crotaphytus collaris, is one of North America’s most colorful reptiles.  Alert and active by day, Collared Lizards housed in planted desert terrariums make for stunning displays.  They also possess distinct personalities, accept gentle handling, and, being relatively easy to breed, are now available in a variety of interesting color phases and patterns.  The following information can also be applied to the related but less-commonly kept Leopard Lizard, Gambelia spp.

Taxonomy, Range, and Habitat

Nine species of Collared Lizard have been described.  In the pet trade, the name “Collared Lizard” is most frequently applied to Crotaphytus collaris.   Five subspecies of Crotaphytus collaris range from the central and southwestern USA to central Mexico.  The Eastern Collared Lizard, Crotaphytus c. collaris, is the subspecies most commonly kept in captivity.  Its range extends from southern Missouri through northern Arkansas and southwest to central Texas.  Different Collared Lizard species hybridize in captivity and the wild.

The related Leopard Lizards (3 species, please see photo) have been reassigned to the genus Gambelia.

Collared Lizards are usually found in rocky deserts, overgrown thorn-scrub and other arid habitats. Read More »
