I believe the first batch was released by the male the night of the 2nd. It looks like last night he received another batch from the female.
I can see a real difference between these eggs and the last batch; it really makes me believe that I hadn't noticed the last batch for several days. That batch had visible eyes; these eggs seem smaller and have no distinguishable features.
I have all the equipment to keep a rotifer culture going... but haven't found a source yet for SS-strain rotifers. Anybody have advice? Reed mariculture doesn't seem to be carrying them.
