Hiya! I'm Madelyn, and I am 14 years old. Recently, I came to get some tadpoles from a neighbor's unkept pool. As far as I can tell, they are chorus frog tadpoles, though I may be confused since I'm new to this. They eat the boiled-frozen lettuce that I give them, and they are doing alright, besides the fact that they are way overcrowded. See, I only have one 15 gallon tank, and close to 100 tadpoles. I know it's very overcrowded (and unhealthy), but there's nowhere to keep more tanks or bigger tanks. So, I guess my questions here are:
How many tadpoles is it okay to keep in a 15 gal. tank?
What can I do with the unwanted tadpoles?

(I'd rather not dump them back into the pool or anything like that because the pool is set to be pumped/cleaned in a week or so.)
