larger reef/invert safe fish??

tangs are great fish and quite hardy maybe you can do a tank with alot of tangs? introduce them all at once when the lights are out they are very territorial so it is best if you were to buy as many tangs as you want to keep all at once BTW it is not uncommon for a tang to eat freeze dried shrimp or any other food you introduce the veggies really help to keep their colors vibrant though! dont know much on butterflies. hope this helps
