Guess I was wrong! On Valentines day I was cleaning out the polyester fiber from my shubunkin tub, and when I looked at the fiber, I saw eggs all over!! And fertilized ones at that - I saw already eyes in almost every egg. So it must have been a few days like this, and I don't even wonna think how much the parents ate.
Took the fiber out and put it into a 10 gl tank with barely half the water in it, a heater and a cycled sponge filter, bubbling only very slowly. Hatching started Tuesday, and most of them are free swimming today, so they got their first meal of microworms and hatched brine shrimp. First count - around 150-200! I'll see if I can take a halfway decent picture, which isn't so easy with my camera.....
