New Life Spectrum (NLS) Betta pellets and Omega One Betta Buffet pellets are the two most frequently recommended foods on this forum.
Bettas need a high protein diet, and the foods that have quality protein (whole fish products) are more expensive than those that contain lots of grains (wheat, corn, soybean, etc) and fillers. Also, feeding lots of grain products can result in constipation and bloating.
NLS is a great product. But it sounds like you got a really big container though. When I was at Petco last, they had a bottle for $3.99, but I'm sure it smaller than 2 oz in size.
I only have a Petsmart near me, and they don't sell NLS. I feed my guys the Omega One Betta Buffet pellets. A 0.61 oz container cost $3.99, and will last a really long time.
So you did get a high quality food, which costs more than the cheaper products. And the larger size means... well, I suppose it means you'll probably reach the expiration date before you run out of food!
