ANGFA launched a crowd funding effort at the convention to raise funds for establishing a genetically tested captive population of the Running River Rainbowfish. This is a joint effort between ANGFA, the University of Canberra and Diversity Arrays Technology. In short, an introduced population of M. splendida is moving downstream into the home of the Running River Rainbowfish. As these two species are quite closely related we expect they will hybridise and result in the loss of this iconic rainbowfish population. As a precaution for this scenario ANGFA is working to establish a captive population based on some earlier collections plus recently collected wild fish to ensure that no hybrids go into the captive population and to ensure that we reasonable represent the existing wild genetic diversity. Fish will be provided to Bruce Sambell, Ausyfish, Dave Wilson, AquaGreen and Aimee and Steve Brooks, Guyra, whom we are working with closely to ensure captive stocks of this fish remain widely available and secure in the hobby. Please consider making a small donation and spreading the word! More details can be found on the donation page. bit.ly/1RZUMht

Great job guys! Keep up the good work! This is exactly why we work so hard to keep our Rainbowfish strains pure. You never know when or how they could disappear from the wild. We are usually worried about pollution, habitat destruction, and other invasive species. But who'd have thought someone would release a different Rainbowfish into a waterway creating this type of problem? Thank you for all you do, and thank you to everyone involved in this project.

Peter. If that did happen. And let's hope not.How many connected rivers and species populations could be affected besides running river.Tried mapping a little on my own but very confusing .

Peter. If that did happen. And let's hope not.How many connected rivers and species populations could be affected besides running river.Tried mapping a little on my own but very confusing . M. splendida occurs downstream of the Running River Rainbowfish too, there are waterfalls that limit their upstream movement, likewise waterfalls limit the upstream limit of Running River Rainbows too. We don't yet know the source of the introduced M. splendida from upstream, but we should be able to work it out via the genetics. My guess is they are from a coastal population near Townsville, but that is only a guess. It will indeed be interesting to see how two different M. splendida populations go during an invasion, something that we'll have to try and track! There is a link to a document that has more details on the funding website (bit.ly/1RZUMht), including a map, but it is not working properly at this moment, hopefully the IT guys get it fixed soon. There will also be an article about it in the next Fishes of Sahul issue too. Cheers Peter

Great article.Very interested in seeing how this all turns out. Such a beautiful little fish. Very sad if this gets lost.
