Newts as Pets – an Introduction to their Care and Feeding

Eastern NewtAlthough my interests are wide, newts and salamanders have always held a special fascination for me.  Beginning in childhood, I sought to keep and breed as many species as possible, and I focused on their husbandry and conservation when I entered the zoo field.  In time, I wrote a book summarizing my experiences (please see below).  The passage of so many years has not dulled my enthusiasm for these fascinating amphibians, and I can highly recommend them to both beginning and advanced herp keepers.

The following information may be applied to the care of Japanese Fire-Bellied, Eastern, California, Ribbed and Paddle-Tailed Newts, as well as most others that appear in the pet trade.  Please write in for detailed information on individual species.

Newts as Pets

An ability to thrive on commercial pellets distinguishes newts from other amphibians, and endears them to folks who prefer not to handle live insects.  All are brilliantly-colored, active by day, and usually live well in groups at average room temperatures.  Most become quite tame over time, and will even accept food from your hand.  Several California Newts in my collection have lived to age 20, and others seem bent on exceeding that.

Cricket Care and Breeding – Keeping Your Live Food Alive

Domestic CricketThe Domestic, Brown or House Cricket, Acheta domesticus, is the most widely-used live food for reptiles, amphibians, tarantulas, scorpions and other pets. At once hardy and delicate, it eats just about anything and is easy to breed, yet a colony can be wiped out in hours if conditions are not perfect.  Whether you need only to keep a few alive so that they can feed for several days (thereby increasing their nutritional value) or plan to save money by ordering in bulk or breeding your own crickets, die-offs can be avoided if you follow a few simple rules.

Primary Concerns

Poor ventilation, crowded conditions and high humidity are the most common reasons for cricket colony failures. These three factors are related to one another, and will be discussed below.

Natural History

Domestic Crickets are native to southwestern Asia. Escapees have established populations throughout the world, usually in close association with people. Their taxonomic order, Orthoptera, contains over 20,000 grasshoppers, katydids and related insects.

The USA is home to over 120 cricket species; my favorites, the bizarre Mole Crickets, tunnel below-ground with spade-like front legs (please see photo).  Over 3,000 species have been described worldwide. New Zealand’s “super cricket”, the Giant Weta, is the world’s heaviest insect…at 70 grams, it weighs as much as a House Sparrow!  Read More »

The Corn Snake and its Relatives – Natural History and Captive Care

Corn SnakeAlso known as the Red Rat Snake, the Corn Snake (Pantherophis guttata), is one of North America’s most beautifully-patterned reptiles, and the world’s most popular serpent pet.  Corn Snakes figured prominently in the development of American snake-keeping, and their history is tied up with the legendary Carl Kauffeld and his famous collecting site, Okeetee, South Carolina.  My own history leads me to Corn Snakes as well…I was in awe of Mr. Kauffeld as a child, and in later years I was the consultant for the renovation of his beloved reptile house at the Staten Island Zoo.  So, despite having crossed paths with hundreds of species, I reserve a special fondness for these interesting, undemanding beauties.

Recent Name and Classification Changes

The taxonomy, or classification, of the Corn Snake and its relatives has recently been revised. All have been moved from the genus Elaphe to Pantherophis; several species have been combined, and new ones have been described.  We are left with the following (please see article below for details): Read More »

Chameleons as Pets – an Overview of their Natural History and Captive Care

Chamaeleo calyptratusChameleons, the most unique of all lizards, are truly marvelous creatures to know and care for.  In the past, I’ve written about Veiled, Dwarf and Senegal Chameleons, and related topics (please see articles below).  Today I’d like to discuss some general principals of chameleon care.

The following information can be applied to most available Chameleons; however, details will vary.  Please write in for specific information on individual species.

Natural History

To date, 186 Chameleon species have been described (Family Chamaeleonidae).   They range in size from the 1.5 inch-long Pygmy Leaf Chameleons (Rhampholeon spp.) to the Oustalet’s Chameleon (Furcifer oustaleti), which may top 30 inches in length.

Unique characteristics include a tongue that may exceed the animal’s length, mobile eyes, a “swaying” walk that mimics wind-ruffled leaves, joined toes that form grasping “hands”, a prehensile tail and remarkable color-changing abilities.  Color changes are mainly used to communicate, but also serve as camouflage.  Read More »

Hatching Praying Mantid Egg Cases to Feed Tiny Amphibians and Invertebrates

Mantis Laying EggsDietary variety is the key to success in rearing many herps and invertebrates.  Unfortunately, options for newly-transformed frogs and salamanders, Poison Frogs and other small species and hatchling spiders are limited. A diet of fruit flies, springtails and pinhead crickets sometimes suffices, but as I learned when rearing the endangered Kihansi Spray Toad, other foods are often necessary.  Praying Mantid Egg cases (properly termed “oothecum”), which may be collected or ordered from commercial dealers, are a useful but under-appreciated resource for those who keep small insectivorous pets.

Foreign Mantids in the USA

The 2 most-commonly encountered mantids (or mantises) in the USA are both introduced (not native).  The largest and most widespread is the Chinese Mantid, Tenodera aridifolia sinensis, brought here in 1896 to battle insect pests.  The European or Praying Mantid, Mantis religiosa, arrived as a stowaway around the same time.  They and the world’s other 2,400+ species, consume vast numbers of beneficial and harmful insects…in fact, a single Chinese Mantid may consume 20,000 or more insects in its lifetime!
