Well this is my first tang and has been a learning experience too. I read for about 1-2 months before buying him and thought I was up to speed..but wasnt...BUT he is doing well now. Selcon, Zoe, vitamin C are all supplements to be added to the Nori...or seaweed. Nori is seaweed that you can buy in most grocery stores, whole food places, or Asain markets. Or use Julian Sprungs (spelling) seaweed. The supplements will help him have a healthy immune system. I was a little leary at first as everyone was telling me to use these things...I didnt see how it would work but it has. My tang was so bad, that his face and all down his back had turned white....basically lost his color and started getting bad pits in his face and lips...now he is about 85% healed and is eating well.
The garlic will increase the fishes appetite...add this to the Nori (seaweed) as well. Dont forget vitamin C too!! Tnags are needy!!
