How to make Brine Last Longer? Feed them?

[flipper]

I have my african dwarf frogs on a brine shrimp diet. My local fish store gets a new batch of brine every Wednesday. Problem is I get them on Wednesday and by Saturday or Sunday their all dead leaving my frogs starving for 3 or 4 days. Tried feeding them Spirulina Powder but after it settled to the bottom of the tank all the shrimp died within a day for some reason. I've heard some people to feed them Liquid Phytoplankton .


Tank Conditions where Brine Is kept:


- 1 Gallon Tank


- Brackish Water Measured with a Specific Gravity Meter to be just right


- Air Pump kept at top of tank because when I place it at the bottom all the shrimp start whirling around like a tornado smashing into walls


- Waters kept around 70 degrees


I guess my question would be is their anything I could feed them to make the shrimp last longer than 4 days.

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.
