Fish ID ?

[Salty]

Yes, "tang" is the more common name for surgeonfish, especially in the aquarium trade. Blue Tang, Yellow Tang, Unicorn Tang, etc.
Fun fact: They get the name "Surgeonfish" from the sharp, blade-like spine in front of their tail on each side of their body. They are territorial and will aggressively use these spikes to fend off other fish or potential threats by side-swiping their targets. So if you happen to catch one again, be careful when handling them!
