I to was tang nuts in the beginning of this hobby. I had 4 in a 90! Man i learned the hard way. My yellow was one that i did keep though till i moved and he/she was pretty calm with the other fish. If yours gets nastie sarah just try all the basics apon additions and rescape, feed well before, add in the evening just as lights go out. These three things will help alot. Also if ou want to keep more then one tang its best to have three. Two is just asking for a war. The third seems to be a reef.
