This is a cute little Freshwater Shrimp about 3cm long. He isn’t fully grown. Like a lot crustaceans he lives in water (yes there are some exceptions). When he reaches adulthood he will be black and 7cm long. They don’t make very good pets though! I had one for one night, and it died overnight. I’m not sure why, but a possible reason was that it was too cold. Funny thing is though, is that some little ones survived. When I realised that they survived I let them free in the creek out the back of our house where they came from originally.
Their relatives include yabbies, crayfish, lobsters, crabs, and mantis shrimps (aaarrrrgghh!).
