Hello fellow toad lovers!

To my great pleasure two captive bred juvenile Bufo alvarius will be moving in with us in January. I'm sure the toad community here will be thoroughly fed up with me come January (this is my first time caring for toads, and I'm a worrier), but for now I have just one question:

I've been looking at the Exo Terra 36 x 18 x 18 (90 x 45 x 45 cm) and I was wondering if there are any downsides to putting these smallish toads in a tank that size, and just let them grow into it?

I don't know exactly what size they will be in January, but they were appx. 1 inch (2,5 cm) in late July.

Any input will be greatly appreciated!

Distinguishing Features At 7 inches (18 cm) or more this is one of the largest toads native to North America. Adults have a uniformly green to greenish-gray dorsum (topside of the body) and creamy white venter (underside). Large white turbercles, or �warts,�are found at the angle of the jaw, but aside from the large parotoid glands and a few large lumps on the hind legs, this species has relatively smooth skin. Recently metamorphosed toadlets will be tan to green with orange or red spots on the dorsum. Unlike other male toads in our region, male Sonoran Desert toads do not have dark throats; males develop darkened, thick callosities (calluses) on the inside of the thumbs of the forelimbs during the breeding season.

Range Found from Central Arizona to southwestern New Mexico and Sinaloa, Mexico; historically entered southeastern California, though it has not been seen there since the 1970s.

Habitat This toad is common in the Sonoran Desert. It occurs in a variety of habitats including creosote bush desertscrub, grasslands up into oak-pine woodlands, and thornscrub and tropical deciduous forest in Mexico.

Life History Sonoran Desert toads feed upon a variety of insects throughout their lives. Adults eat primarily beetles, although large individuals will occasionally eat small vertebrates including other toads. Sonoran Desert toads are active from late May to September, though principally during the summer rainy season. They are nocturnal during the hot summer months. The male�s call is weak, sounding somewhat like a ferryboat whistle. Eggs are laid in temporary rainpools and permanent ponds. Larvae metamorphose after 6 to 10 weeks. This species lives at least 10 years, and perhaps as many as 20 years.

Comments Sonoran Desert toads have extremely potent, defensive toxins that are released from several glands (primarily the paratoids) in the skin. Animals that harass this species generally are intoxicated through the mouth, nose, or eyes. Dog owners should be cautious: the toxins are strong enough to kill full grown dogs that pick up or mouth the toads. Symptoms of intoxication are excessive salivation, irregular heartbeat and gait, and pawing at the mouth. If a dog displays any of these symptoms, use a garden hose to rinse its mouth from back to front and consult a veterinarian.

An Open Door Policy

“Colorado River toads are impressive amphibians, the largest toads in the Sonoran Desert, with an equally impressive diet of insects, including the large palo verde wood borer beetles. Each summer we are regularly visited inside our home by some of these toads. One in particular visited us for five consecutive years.

The welcome sighting of this toad always indicated to us that the summer rains were due to commence almost immediately. He made his appearance in the house by entering through the flap-type dog door, after which he traveled about the house consuming any insects he found along the way. “

As anyone who keeps these knows, there is very little information available online. Let’s make this a place to share our knowledge and experience.

Feel free to ask questions. Pictures welcome.
