I wanted to add that there are more and more vendors doing this. LiveAquaria has an aquacultured area as well as most of the better vendors out there, even small ones.Excellent - thanks. I wanted to set up a reef tank a long time ago but couldn't justify taking marine life out of the wild (everything that goes with that) and then with a good chance of stuff dying (especially back then).
I'm comfortable enough now that I can do it with minimal impact so I'm pretty excited to give it a try. Gradually building my knowledge from the forums here and a few other places.
Lots of great info here!
