Does anyone belong to any local aquarium clubs? How about national clubs? Many of these clubs are involved in conservation. For example, the American Cichlid Association. http://www.cichlid.org/
Their mission statement shows this:
1 - gather, organize, and disseminate knowledge of the family Cichlidae;
2 - encourage and further the study and conservation of cichlids, in their natural habitats and in the hobby;
3 - encourage the study and preservation of cichlids by awarding grants for research and conservation;
4 - further the conservation of the natural habitats of cichlids;
5 - provide a means for individuals to acquire and distribute cichlids; and
6 - promote fellowship amongst the members.
They are also part of CARES (Conservation, Awareness, Recognition, Encouragement, Support). http://www.carespreservation.com/ They try to have people keep highly endangered fish in their aquariums long term in the hopes of breeding them and passing them along to like minded aquarists so that the species won't be lost due to extinction.
