Tangs are probably one of the best examples.
you couldn't have said it better trojan. after seeing the cahnges in the behavior i will never keep any of the larger tang species ( Acanthurus, Naso, or Paracanthurus)in anything less than a 6ft aquarium. however yellow, purple, and kole tangs i feel can be kept in 55gal tanks, obviously one per tank.
