I fed it brine shrimp and squid mix and they ate 'em crazy... well I guess I'll try to sell one of my yellow tang... btw I think they're all fully grown. I like the humu better so I think I will keep that.. also, before I left... one hermit already died and my starfish likes to eat snails for some reason.. so I guess nycfatcow is right.
What size tank did the previous owner have? Because if it's anything less than a 150 I wouldn't entirely trust their opinion. And if it is something above a 150, fish are going to act very differently when scaled down to a small tank like a 75 g.
Triggerfish can be relatively peaceful then one day they'll snap and turn into these serial killing monsters they have the reputation of being. Mine was very peaceful until he killed two fish one night and we had to find a new home for him. There are countless other similar stories with triggerfish. They are also pretty active swimmers and need more room than a 75 g can provide.
Yellow tangs are herbivores. That doesn't mean they won't eat brine shrimp, mysis, other meaty foods - but they don't get the nutrition they need from those foods as they do from herbivore preparations so the vast majority of their diet needs to be food for herbivores. Not to mention even LiveAquaria which tends to underestimate tank sizes says a yellow tang needs at least 100 gallon. The sailfin needs 125g according to LiveAquaria.
