thats true. they are so tiny. I'm still going to switch the substrate to dirt and rock, planted plants. I'm going to leave the little pond with filter (this way I do not need to mist or change the water everyday), and then do a complete canopy to triple the land space in the tank. As I said the other tadpoles are not really developing one or two has had the outline of hind limbs for about a week and my two fatties have nothing as of yet. Could that be due to the falling temps?
