Help with raising common frog tadpoles

[kueluck]

I've raised about 60 tads (grey tree frog & native toads) in the past few years with only a few of them not making it to froglet stage. I would boil romaine lettuce for one minute, let it cool, then sink it to the bottom with a large stone. I would cook it fresh each day and if there was anything left over from the previous day that would be removed. After they started to grow I would use tadpole pellet food a few times a week, but they seemed to love the lettuce over anything else. I also changed out 50% of the water twice a week.
