| I LOVE purple tangs...one of my top 5 favorite reef fish. BEAUTIFUL, and great for the aquarium. They will get ich occasionally if anything is awry in the tank, but they are pretty good once established. I pretty much expect that when I add a purple tang, they will have some ich that will clear up.
Mine always LOVED mysis shrimp...and I gave him nori constantly too. But man....that fish could DOWN the meaty foods. It was like he had never eaten every time I fed the tank!
