Care for American Toad Tadpoles
Most
amphibians begin life in the water, "breathing" with gills.
Early in spring male Toads gather on ponds and call to attract females.
The American Toads (Bufo americanus)
at Powell Veterinary Clinic laid their eggs in our pondlet
Saturday, April 18, 2009
. They hatch
in 3-12 days. One female can lay 12,000 eggs.
Tadpoles
(the young of frogs and toads) tend to be herbivorous, eating algae and
other plants, but also scavenging dead animals—including other tadpoles.
Keep the tadpoles in 2-6
inches of clean pond water (or dechlorinate tap water by letting it sit
out for 24-48 hours) in an aquarium or other container, and change a
portion of the water frequently. You can use bottle spring water, but
NOT distilled water. Debris can be sucked out with a turkey baster. You
may use a bubbler in the water to provide more oxygen, but don’t use a
filter, as the little tadpoles may be sucked in.
Do
not crowd tadpoles. It is best to keep just a few. Sometimes they will sit
on the bottom of the tank and look dead, but usually they will move again
after a while.
Tadpoles
can be fed algae or soft water plants. They will also eat softened flake
fish food and the boiled (softened) leaves of dandelion or dark green
lettuce (boil lettuce for 20 minutes, then freeze and just scrape off a
portion at a time).One of the easiest ways to feed them is to keep a
package of frozen spinach in your freezer, and scrape off small amounts to
use. They can be fed flake fish food too. Don’t over-feed, as this will
foul the water.
As
the tadpoles’ legs develop and they begin to look more
"frog-like," provide a sloping rock or other object so they can
climb out of the water. As their lungs develop, the froglets will drown if
they are unable to leave the water.
American
Toads may take 5-8 weeks from hatching to the end of their metamorphosis
(when they develop legs and climb out on the rock). They will stop
feeding during transformation. New toadlets eat extremely tiny insects
("fruit-fly" size) and are thus very hard to feed—it
is best to release them in proper habitat (a moist garden-like area
with plenty of plants or brush to hide under, preferably with access to
water) soon after full
transformation. The newly transformed toadlet may still have a small
tail.
Try
not to touch the tadpoles or tiny frogs with your hands, as soaps and
lotions may be harmful to them.
