After raising these little frogs, I have noticed that there are 3 requirements that should be fulfilled to raise tadpoles succesfully.
1) Tadpoles require slightly alkaline water (pH 7,6 - 7,8).
2) They require extremely small, but alive food items. In the first phase I used zooplankton raised separately and/or transferred from other aquarium. After tadpoles had grown a bit, first stage artemia nymphs were used. (These nymphs can easilly be raised in small scale without pumps, airfilters etc. usually stated as mandatory. All you need is two flat dishs, water, some salt and good quality artemia eggs. And some extra time to run 2 cultures parallel and reconstruct them every two days.)
3) Tadpoles are very sensitive to changes in water quality. Only a small fraction of water should be changed at one time, but changes must happen regularly. I used to change one fourth of the water daily, or sometimes a smaller fraction twice a day. I always took incoming water from well functioning, big aquarium (populated by adult ADFs). This way it included some zooplankton, and did not include harmfull chemicals.
My experience is that raising ADS tadpoles is not very difficult, but it takes more time than raising many other tads.
