I would say that the amount and frequency that you are feeding them is PERFECT, if anything it might be a little much. One of the problems with captive reptiles and amphibians is that they are usually overfed. People insist upon using what they know about dogs and cats and applying it to reptiles and amphibians. Always remember this: 80 percent of the food that we eat goes towards making body heat. That means that the vast majority of the food that we eat is lost to the atmosphere!! We are energy wasters!!! Ectotherms, on the other hand, use most all of the food that they eat for conversion to biomass (biomass equals new skin, leg muscles or fat etc., whatever). This means that they do not need to eat as often and as much and endotherms.

Login, then go to upload pictures. When you make a new post, there is a drop-down menu under the red OR: where you can select the image you just uploaded. It really is simple. And there really is no way to correctly identify your tadpole from that description.
