Thanks Jim ... always not quite what I want happens.... it was the wrong p.oblonga tank

the other one has the albino in it (did I mention/show it to you?) and I was hoping that group spawns.
But looking at the babies, I think this is not possible yet. Oblonga seems to grow really fast to about 1.25" (2-3 months) and then stalls, the babies from the last year spawn, in the same tank, at still only 2" and I could not see any gravid females ... heck, I cannot sex at all. Maybe they need to be 2 year old or even older before they get mature? (and the group with the albino is also 1 year olds, with no sexual differentiation I can see).

Actually I should show you one day the other kuhlis in that tank... unusual.

Regarding feeding your fry: this is what I did and I think this helped with the survival of young hillie fry: take good powder food (Sera Micron or APR), put it into a cup and stir until it sinks (it is designed not to sink, so top fish babies can eat from the surface, you want it one the bottom rather than in the filter), then pour it into the tank with fry. This will not help your fry much, it is already too large, but there may be smaller ones you don't see... spotties are serial spawners.
