How to Raise Baby Frogs

Frogs, small amphibians that subsist mainly on insects, worms and minnows, can make interesting pets. To raise a frog from a baby to an adult, you should start with a tadpole, which will metamorphose within a few months into a froglet, or baby frog. With good care, your froglet will grow into an adult frog, which can live up to eight years in captivity. You can collect tadpoles from ponds and streams in the springtime or buy them captive-bred. Tadpoles you collect probably will turn into green, pickerel or leopard frogs, all of which can do well in captivity. No matter what type of tadpoles you have, the metamorphosis, which takes roughly 90 days from egg to full-fledged frog, is fascinating to watch.

Instructions

    • 1

      Check your local laws to make sure collecting wild tadpoles is not illegal. If so, you can always buy captive-bred tadpoles, which have the advantage of being guaranteed disease-free. If collecting wild tadpoles, you don't need more than a few.

    • 2

      Use a 10-gallon tank of glass or plastic--complete with a screened cover--to house your tadpoles. Place a half-inch of aquarium pebbles on the bottom and add dechlorinated water to a depth of 4 to 8 inches. Let the treated water sit overnight to get rid of any residual chemicals. Tadpoles are very sensitive to chlorine.

    • 3

      Landscape the tank with store-bought aquatic plants, which provide both aeration and hiding places for your tadpoles, and stacks of rocks that tadpoles can use to leave the water when metamorphosis is complete.

    • 4

      Keep the water temperature between 65 and 75 degrees F; a heater should not be required if you keep the tank in a place with normal room temperature.

    • 5

      Feed the tadpoles lettuce or spinach that you've washed and boiled for 15 minutes. You also can offer commercial tadpole food and bottom-feeder algae fish food. Supplying small feedings a couple of times a day is preferable to giving one big feeding.

    • 6

      Do a partial change of the water every three days, replacing the dirty water with dechlorinated water. Tadpoles have gills, like fish, and have the same requirements for clean water.

    • 7

      Set up the permanent home when tadpoles have their rear legs and are beginning to develop front ones. To provide the semi-aquatic environment most frogs need, you can use a piece of plexiglass and silicon sealant to divide the tank into a water area and a land area, or simply slope pebbles to form a natural ramp onto the land area, which can be formed by covering gravel with some moss.

    • 8

      Offer the small froglets baby crickets, wingless fruit flues and small waxworms--none longer than 1/2-inch--when they have all four limbs and are spending more time on land than in water. The froglets might still have tails at this point, but they will be reabsorbed within a day or so. Don't worry if the froglets don't eat for a day or two while their tails are being reabsorbed: They are getting some nourishment from their tails. After this, they should be ravenous and attack the insects with gusto.

      Begin offering full-size crickets and waxworms as the froglets develop into mature adults.
