D. retics dance for six plus hours before laying their eggs.
The breeding dance movements are jumpy and much like this animations.
Actually the exposures were one second long and I only lost one shot to a blur.
The retics get together in a group and dance around the tank in short jerky movements
with stop motion stills between movements. So as soon as one moves they all stop motionless
until the next one moves. The males call in a tone I can't hear but multiple males and females dance together.
I can't help but to wonder how different the dance would be in 200 square feet rather than their current three square feet.
