Welcome to Canreef Cougarman (and your sweet 600G tank!)

[Matt]

You keep tangs in a 600? How are they supposed to find room to swim?

Anyone who keeps any wild animal in captivity is automatically part of the 'problem'. There is very little moral high ground. We ALL do it for selfish reasons, not for the well-being of the animals. We - none of us - 'saved' a tang from the local shelter. We condoned its wild capture (and the death of several others for every long-term survivor). I'm OK with that. I also condone the death of cod, haddock, sole, and many other varieties of fish. Because, selfishly, I find them tasty.

Keep tangs in a 10 gallon, if you find that satisfying, as far as I'm concerned.
