You do realize chevrons are one of the hardiest tangs you can purchase right? Expensive doesn't always mean hard to keep..
I don't want to sound like I'm attacking you, that is not my intent. It's just that responses like this are a huge pet peeve of mine. A hobbyist asks for information on a fish on the more rare end of the spectrum. Then all I see is replies like the above, "If you need to ask you aren't ready to care for one."
Considering this is the mecca of reef information for the most part, where do these people expect hobbyists that are ready to jump to the harder to keep fish get their information?
