You folks are amazing. Some very, very thoughtful commentary going on here. I am impressed.
Couple of things:
Jamison: Thank you for making me really think. Something bothered me about the examples you gave (K-Mart vs. the Gap, etc.). Those examples are all (nonliving) quality-of-life things. The fish we're discussing ARE life. That makes the difference ... I haven't entirely got it figured out yet, but therein lies the answer to your question. I'm still working on it ... and yes, I agree, RTR stated it masterfully.
Re: inspiration. Kribensis are common fish, right? I submit that anyone watching a pair of mated kribs herding their fry around the tank and guarding the nest will be inspired. I was. That's what got me into this as a serious hobbyist, and I still shoot for my favorite fishie dream: a successful tank of breeding Blue Rams. Sigh. Something to hope for ... and work for--and, in an area where the tap water comes out 7.6 pH, believe me, it's plenty challenging!!
Again, thank you for the thought-provoking post. And the answers! Boy, we sure all love our fish, don't we. It goes back to that life thing ...
