Congrats dad! Best of luck with them!
Just in case you want some other foods, you may also try http://www.kensfish.com/
for a good cheap source of bulk foods.
I've had good success with a blend of stuff from there.
I mix the following:
1 Tsp. Decapsulated Brine Shrimp Eggs,
1 Tsp. Golden pearls
1 Tsp. Kens Premium Growth Meal (#00 SIZE)
In a small shaker top bottle and feed a little
bit of that blend 3-5 times a day.
The rest of the bags are stored in the fridge until I need another mix.
I also hatch some live Brine, but just don't have the time to keep up with the production.
Later on, I use Grindal Worms mixed in with that blend. For me, grindals are the easiest live food to grow and propagate.
