Hi herald
I too, like tangs.
Achilles and Powder Blues being on the top of the list.
Aside from being the prettiest of the bunch (IMO

) they also seem to be the hardest to care for. Powder Blues especially (probably because they are more common than Achilles) seem to be the topic of many a heartbreak post on the reefing boards; I had my own go around with one
The keys to keeping them healthy and happy are top-drawer water quality, good nutrition and lack of stress (whether from confining tanks or from tankmates.) A mature tank, feeding selcon soaked Nori (occasionally soaked in garlic as well) and live "greens" like our sponsor ISPF's Tang Heaven will go a long ways towards your success with them.
I had a
Kole tang that I really liked and who was doing very well until he fell victim to a dinoflagellate outbreak. He was a very placid fish if a little shy. I gave to a friend a yellow tang I had for quite a while that was tougher than nails and was always out in the open. I have three kids at my house and with all the banging, yelling and running, he was still never shy and never had a spot of ich. Definitely kid tested
