Need help quick!!! ID this tadpole?

Apparantly this was a stowaway with the goldfish that came into my sisters petco..

We dont know what to do with it to keep it alive o_O

I work at a petsmart and we get those and crawdads with our goldfish as well. It's a bull frog tadpole

I raised a couple and all I did was weekly water changes (makes sure you use conditioner/declorinator!) and fed them top fin tadpole/frog/newt pellets. They seem to be pretty hardy little suckers too :)
