An update, for those bored enough to read it!
Mrs. Pink Bolt (she's not very red ?) got impatient and molted this morning with about 8 eggs left on her old swimmerets. I fetched out the molt, removed the eggs, and placed them in a strainer near the output of the filter. Of the eggs I found, 3 were sorta hatched, but dead (sadly, 2 were bluish). Many hours later, as I was about to turn out the lights for the night, I checked and the 3rd bluish egg had hatched! RAWR!!! Mrs. Pink Bolt is already berried again...
And I TRIED to take pics of the babies... but I lack the nifty do-das, so you mostly see a slight, pale bulge on the side of a piece of moss.
