The chances of someone - out of the blue - bringing a Tropheus colony or a dozen or more high quality fry to sell in one of our monthly auctions is low. Stranger things have happened but it's just not likely. Especially with the prices that things tend to go for in our auctions.
That said, there lots of great reasons to come to CCA meetings other than to buy stuff.
World class speakers and hanging out with other fish geeks come to mind. We had the guy who leads The Nature Conservancy's Programs in the Lake Tanganyika region as a speaker last year. As well as Anthony Tu on Frontosa. Probably forgetting other Lake Tang-focused speakers (aside from Ad Konings, of course, who gave a Lake Tang and Lake Malawi talk at AquaMania last year...and Pam Chin who covered both this year). We try to bring in a mix of good speakers.
Interest and the number of people keeping one kind of a fish or another comes and goes in the club. There used to be more people keeping Tropheus in the club...there still are a few...but there are lots more people keeping other kids of fish that they didn't in the past.
If you want to get people excited about keeping Tropheus, join the club and get involved with the others in the club keeping them...or bring folks in the area who keep them but haven't joined. Sell some extras in the monthly auctions... In the end, CCA is a community of folks with relatively wide interests... and groups of folks with specific ones.

Just my opinion, but I think it is tough with some of the niche cichlids that are out there. Two the jump to mind are tropheus and discus. Both have a reputation for being hard to keep, although for very different reasons. Both are relatively expensive to get started with (and even more expensive when you have a learning curve). Both are probably not as difficult to keep if you do it right the first time, but until folks have the space and desire to do their research and keep these fish properly, they end up being to "scary" and folks stick to what they know.
