Thanks for the info. I started feeding some romain salad also. I put it in the freezer first let it freeze then rinse it , then feed it. They all love it. I have other fish in the tank that just love the meats , and the tangs likes it too. I feed small amounts several times a day, so they seem really happy. My tang will eat right out of my fingers he is not afraid. It seems as though he wants to be petted. LOL. What other vegies from the store can I offer the tangs?
