Additional Information
I initially purchased two fish and placed them in a breeder net in the 10G. Within a hour one had jumped out of the net and into the tank, so I figured they were both the same sex. It took a few weeks for my LFS to get more in. Today I returned one and picked up another. It's slightly bigger and seems a but "plumper" as described by Witt. They appear to be getting along, we'll see what happens. New pair was acquired 09-12-2011.
First hatch was on 03-04-12, about 50 hatched. On the 5th about 75% of the eggs remained unhatched so I shook the pipe as suggested and the majority of the rest hatched. Estimating I have ~150 now.
