Tank size for Tangs? An evaluation...

[Troy F]

>I will start by saying that a fish having a brain the size of a pea cannot be happy or unhappy<

I know people that have similar traits and they appear happy.

>Is a 180 really any better, compared with the home we took them from? No.<

I couldn't disagree more. There's no comparison.

>I read in my previous post that someone purchased a 1.5 cm juvnile tang for a 70 gal tank and that it had died by being caught into the overflow.<

Actually Doug's tank is a 170 and honestly, he thinks it couldn't handle the current but it's just his guess. It's possible that it didn't handle the stress of lights out or any number of things and that is where it ended up. The argument that, "if I don't buy one, someone with a worse/smaller set up will" isn't very strong. If the people without proper systems stop buying unsuitable fish, the stores will stop carrying as many.

>I also keep a tang in my reef to study it's behaviour not just because of it's beauty.<

What would you be studying about a surgeon fish's behaviour in a 33gal tank? It's natural tendencies?
