Here are some basic steps for taking care of the tadpoles. The tadpoles can go up to 3 days without food! Those little creatures... magnificent... Well anyways... the food that they eat is different depending on their age. The tadpoles are herbivores but, when they are actual frogs, they are mostly carnivores. The type of water that you need to survive is either spring water, or tap water (filtered). You should change it when it is getting a bit dirty, kind of cloudy. If the water goes cloudy then you would want to change the water more often or, if the water stays pretty clean then you could change it less. The average basis is changing the water 2 times a week (or more).
Boy, taking care of 5 tadpoles is very hard work.... I mean you think that is a lot of work, but that's only like 1/4 of the process.... Anyway, the next part is you need to put in first is some ground. Gravel or dirt is recommended.
