After a very long wait, I have finally got my hands on a dozen of these fellows. Size is slightly less then an inch.
An updated picture of my setup, without flash and a rare shot that managed to capture all 12 pieces.
Here's a video of them feasting on frozen daphnia. They are almost an inch now.http://www.youtube.com/watch?v=zfW4UG0kgzg
And this is a video of them, don't know
busy doing what.http://www.youtube.com/watch?v=L3SWvI_ZLH4
