Congrats, Bob. I'm a little surprised they decided to go this early, but...
Most Fundulus have fairly large eggs, 1.5-2.0 mm from what I've heard and
seen. I know that diaphanus deposit their eggs in rooted plants most
typically in nature. The one thing I wasn't sure about was how likely they
are to eat their own eggs. Yikes! I want to try to breed some F. euryzonus,
and I suspect they would also much prefer floating surfaces for their eggs;
like notatus and olivaceus they're _really_ topminnows. I'll have to make a
push to feed them well twice a day; usually I do one large feeding daily,
and they at least look in good health.

Good luck with your leg!
