Many of us that now consider our hobby as the ultimate challenge started by raising various fresh water species. I am still very fond of African cichlids and plecos. The line that separates us is not as thick as we like to think though. Consider the challenges of establishing a successful planted ecosystem versus the challenges of a reef ecosystem. They both require a vast amount of knowlege and work to make it happen. With that respect given, I am not really interested in meeting with such a vast group of aquarists. I'd rather have something developed just for reef keepers.
As far as the zoo project is concerned, there are many displays of freshwater fish integrated into Destination Africa. People can learn about the real importance of cichlids and barbs while visiting the hippo exhibit.
Why not teach people about the real importance of preserving our reefs? IMO they are more beautiful anyway.
