Hello. The main food is LRS reef frenzy. I'm feeding 2-3 times per day. I also mix in some PE pellets, New Era algae pellets, frozen mysis from San Francisco Bay, Ocean Nutrition formula one, and a saltwater multi-pack from San Francisco Bay, as well as nori sheets every couple of days. All the fish except one eat about everything. That one is a Spotband butterflyfish (Chaetodon punctatofasciatus), that I haven't seen eat anything. I got an order of copepods that I put in the tank a couple weeks ago, but not sure if they are still there or not. I'm currently trying to hatch some brine shrimp, and will try feeding some of those. I was just thinking that live food would entice him to eat, and would also like to start feeding the black worms, or white worms, to all the fish.
