Just a note for concerned people, frog tadpoles are brown and you can see the fins on their tails, cane toad tadpoles are black and their tail fins are transparent, so their tail just looks thin and round.

A couple of days before I had gone down the local creek and collected some river sand for the bottom of the tank. I had also filled a plastic container with water and let it stand for a few days so that all the chlorine had evaporated.  You must use a plastic or glass container, not metal, and do not fill their tank with rain water collected from a metal roof.

Three weeks later some of the tadpoles had developed back legs, and scared that they would transform into frogs overnight, I added a large rock from the garden to help them out of the water. When tadpoles morph in to frogs they lose their gills and may drown in their tank.

There was no need for me to hurry though, as two weeks later, only 4 tadpoles had turned into little frogs, and they were quite adept at climbing up the sides of their plastic tank. Over the next two months it was a non-stop frog nursery, and I kept finding little frogs all over the place. On any of those days I would have counted ten or more little frogs in and round the tank, I was so pleased, but slowly but surely they all moved away. I am now left with my guppies and neon tetras and a large population of snails.

To comply with dengue regulations, you must have guppies in your tank with the tadpoles. Guppies eat the mosquito larvae and pupae, and the tadpoles also like the fish flakes.
