I have some tadpoles that I rescued from a man made pond that was drying up and I keep them in my feeder tank.They are probably bullfrogs,no limbs yet but I guess I wont be sure untill they become frogs,I keep them in my feeder tank for now where they eat flakes and sinking pellets.I would like to know if there is anything else I can feed them or what else I can do to help them along.I'm guessing that they wont become frogs untill spring or fall,any advice.
