An alternative for the beginning is vinegar eels or microworms. Microworms tend to foul the water a little and sink to the bottom, vinegar eels swim towards the top, bringing the fry off of the bottom.
If it were just size of the food you could crush a quality flake to powder & be done with it. The motion of live micro foods stimulates the feeding instinct, especially during the first few days. Often angel fry need this to begin eating. This is the main reason liquifry & other foods don't work well.
It's all new to me
So far I've had Platys (just add water), Goldfish and Comets (no intervention neccesary usually, apart fom last year, when I brought eggs in on some plants by accident. 6 from 8 survived and are back in the pond) breeding succesfully , but I've had no luck with our Angels, Corys, or Danios.
I've sent for a NT LABS bs kit and it was despatched yesterday.
Yesterday was the first time I could see eyes and the wigglers are still clinging to the internal filter box.
Maybe the kit will get here in time.
Thanks for everyones' help. It's appreciated
