I have just breed dwarfs about four weeks ago, for the first time. They are doing well. I found haveing inforesoria and micro worms a must and on tap.Keeping tank coved in glad wrap.,One thing i did wrong was not haveing another tank ready. They grow at different rate, so the bigger one need to be taking out, otherwise they eat the small ones.Now also giving a speck of crush flakes.Good luck in breeding them. Hope this helps
