More then 50% of farm expenses goes into feeding bettas. The bettas are fed live cultured food, like tubifex worms and daphnias(AngBoon). Cultured live foods are expensive, this is partly due to transportation costs, since they cannot be bought in bulk and stored. Brokers purchase live foods (from Malaysia) and pack them in plastic bags filled with oxygen and make daily deliveries to the farms. Occasional treats, like frozen bloodworms and guppy fry provides variation and supplement their normal diet.
