Thanks :) Like any pet, the initial setup is the longest part, though tadpoles definitely take much more time than frogs due to the amount of attention to detail required to rear them correctly.

Once you're into a daily routine, I'd estimate it takes about 5 minutes to feed, 10 minutes to test the water, 20 minutes to clean the tank/change the water, and maybe 25 minutes to rinse off the gravel vac and refill the water bottles (now that I think about it, I might time all of this tomorrow just to see for sure).
