I like to prepare my rearing cups at least a week before the tads hatch. This gives the cups some time to establish a film of beneficial bacteria, which will help to eliminate tad waste and provide an additional food source for the tad. To each cup I add about 1 square inch of Indian Almond leaf (provides tannins, a beneficial bacterial slime and conditions the water), a small section of live water plant ( provide oxygen and eliminates waste) and about 1 inch of fresh dechlorinated water. I keep all my tad cups loosely covered to reduce evaporation and keep any airborn contaminants and dust out. I use a turkey baster to gently move the tad from the deli dish to rearing cup. It is important to be sure the water temperature of both containers are the same. 77°F is ideal, but they can tolerate temps from 65° - 80°F
The tad will not move much for the first few days after hatching. It is still absorbing it’s yolk sack and should not be fed for at least three days. The first feeding should be a very small amount of Sera Micron or other fine fry food. About the amount that can rest on top of the head of a pin. As they grow they can be fed more and varied foods. I use tadpole bites and various flake and pellet fish foods.
Tads are generally fed two or three times a week. Partial water changes every few weeks is beneficial but not mandatory. I usually just suck out the heaviest of waste particles and about 25% of the water with the turkey baster and top off with fresh tempered water.
