I would not feed DACFs a diet of solely brine shrimps. Gave you more food items in your other thread. Brine shrimp has little nutrition unless gut loaded prior to feeding and even then, a one item diet is not good for the frogs. Long term, myself predict your frogs will suffer chronic malnutrition .

To gut load you can use any quality fish flakes or pellets grounded to the consistency of flour. Move that air stone to bottom of container in order to keep both brine shrimp and their food in suspension. Do not worry about them "hitting the walls;" that is the way they are hatched and raised. Once their bellies are full you can use them to feed the frogs.
