Tiny tadpoles starting to swim

My tadpoles are growing up extremely fast. Thursday there were just in their egg stage, but today most of them are already swimming around a bit. The ones I’m raising inside are developing much faster than the ones in the pond, it seems that the warmer and more stable room temperature is doing them a lot of good. Compared to the tadpoles in the jar, the frogspawn in the pond is about three days behind.
