I try to give my fish something different every day. The Bettas really like Ocean Nutrition pellets. I use a variety of dry from Kensfish including angel flake, catfish pellets, and earthworm sticks. Frozen food is more of a treat, and use bloodworms, mysis, or Emerald Entree. Everyone gets fresh veggies 3 X week, they go crazy for zucchini, broccoli, spinach, or shredded carrot. I nuke the veggies in microwave to soften slightly, use veggie clips in tanks. I've had trouble with Hikari foods clouding water and no longer use.
