Well, my 2 cents.
Yes we have fish snobs, but I think we are better than most.
Some prefer less common fish, I do, mainly because you can see the more common ones anywhere and I enjoy the frustrations and heartache of trying to track down, acquire, and keep alive the oddballs and difficult fish.
Nothing wrong with the more common types, it's just I have been there and done that.
Slamming chain stores, a lot of people do (with some justification), on the other hand the best local source for fish around here is Walmart, this one does a very good job at keeping clean and disease free tanks.
Hybrids? I don't care for them but hey, a lot of people do.
Wild caught fish? If it is rare or threarened then I hope to see it captive bred.
Over the years a fair # of the fish I have kept have been wild caught (by me), currently I have LMB, pike minnows, and bluegill.
Oh well, with the more than 20,000 members here we are all bound to disagree on something.
