I've hoped not, but wondered if in tropical climates, people catch and eat Tangs.
I'd dismissed it as I didn't want to think about it, but at conclusion I'd guessed maybe a solitary fisherman with a spear might catch one or two for his family's dinner, but you always imagine the dull boring fish being the ones caught for food... Where the colourful reef fish like Tangs, Angelfish, Butterflyfish and Parrotfish, etc are worth far too much to the aquarium trade to waste them in eating.

Which shows that they're actually caught a lot, there's Clown Tangs, Naso Tangs, allsorts. :cry:
(If you're wondering why the Naso Tang is black, that's the colour they go when pissed off :cry:)
