I have a 48x24x24 tank and will be upgrading this winter. My tangs are all under 6" so far. Building a 6-8 foot tank this winter.

Currently have the fish in my signature below.

Yellow Tang is the most aggressive in my tank and attacks all new additions.

I put mirrors up against the tank when I add new fish. The fish attack the mirrors and leave the new fish alone.

Recently added a sailfin tang to the tank. He swims along side the yellow tang now.
