Those tanks you see with several tangs are usually 300 gallons or more. A naso tang shouldn't be kept in anything less than 8' long.
I agree about the naso...8' or better! I'd just like to add that the OP 'may' have seen some smaller tanks with 15 tangs in it...something like a 90 or whatever...but that doesn't mean the tank was successful. A lot of people take a pic of the tank the day they add 47 fish and post it saying they are 'successful'. Fast forward 6 months and they post another FTS and you see completely different fish in the tank. There's a reason for this. The original lineup didn't work, fish died, fish killed each other, and they have to restock it ever couple weeks. This is not good husbandry. Long story short, the tanks the OP sees that are crammed with tangs are not successful LONG term. Isn't that what we are all striving for? Short term success is useless when dealing with living things.
