Dear Australia Shrimp keepers forum: I am a professor from the University of Washington, in Seattle USA, and I will be on sabbatical leave at Griffith University in Brisbane for six months. I do research on the bioaccumulation of omega-3 fatty acids in aquatic food webs. I am recently a coauthor on several papers that use the fatty acid composition of herbivorous crustaceans to untangle what they have been eating. In general, the types of fatty acids one sees in a crustacean are strongly influenced by their diets. This can be used to back-calculate what wild crustaceans have been eating. so far I have done experiments of this sort on freshwater Daphnia and a marine isopod. I would also like to do such experiments on a freshwater Caridina shrimp, preferably collected from someplace in Queensland, Australia. I hoping for some advice on wild type Caridina shrimp, not fancy types. I am just looking for a strain of shrimp that is easy to grow in aquaria. I plan to feed this shrimp various types of lab grown algae to see how these would change the fatty acid composition of this shrimp. I have no commercial interest in these shrimp. I am just looking to expand the range of organisms that my fatty acid based diet tracing method can be applied to. I have attached a link where one of my papers on this topic can be downloaded for free. I also provide a list of related papers on this topic. http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0129723 Strandberg, U., M. Hiltunen, E. Jelkänen, S.J. Taipale, M.J.

My Pygmy corked are currently spawning. But in a 200L community planted tank I'm never gonna catch em!

Tangerines are indeed Caridina Serrata.

"Oh so natural wholefoods". It's one of those limited time special buys at Aldi. It will be gone by Sat 20 Feb, if not sold out earlier. https://www.aldi.com.au/en/special-buys/special-buys-wed-17-feb/

They won't interbreed but the water parameters for Zebras are different to CRS. That is, you can't keep both in the same tank. Zebras need low, low TDS. Like 40.

Nature isn't always neat and tidy - the wild look works well! My best shrimp breeding tank is a jungle - I don't like it but the shrimp do!

Thanks mate :) Nikon D5100 with Tamron 90mm Macro Lens - Flash is a Nikon SB600. Can share exif info if you like :) (you can also view it by clicking the info button on my site).

Since these lovely shrimp can change their colour quite a lot I thought it would be nice to show some different colours and patterns.
