I was involved in developmental biology research on frogs years ago. We always found the toughest thing for raising tadpoles was getting them through metamorphosis, when they grow legs and reabsorb their tails to become frogs. This is also a time when their entire digestive system reorganizes to go from the herbivore (plant-eating) diet of the tadpole to the carnivore (insect eating) diet of the frog. The process is controlled internally in the tadpoles by thyroid hormone, and is very sensitive to temperature and other environmental conditions.
Steve's advice is good- use water from the pond you found them in, and try to keep the temperature around the same as the pond will be for the time of year the tadpoles are being raised. It will help if you just let the algae grow in the tank that the tadpoles are being raised in; really clean water and clean tank sides is not actually the best thing for the tadpoles. He may find the tadpoles will grow bigger and bigger, but never make the full transition to a frog. We often had these giant tadpoles with only hind legs that just didn't make the complete transition to frog. Introducing some small insects or other invertebrates from the pond into their diet at that time can help them get through the final transition. The easiest way to collect some of them would be drag a fine net through the pond and rinse it out in a small jar of some pond water. He'll probably be amazed at just how many little creatures there are in a small volume of pond water in mid summer.

The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
