Some may not agree with me, Simone, but I would start adding ground basic flake. It seems to start the fry growing quite rapidly when I was still breeding the dwarfs. I would always start all my fry out on the newly hatched baby brine and then after a week start adding ground basic flake. I would also start doing water changes with straight tap water after the fry were 2 months old so that when I sold them to the stores, they wouldn't have a problem with switching from the straight RO to the stores tap water.
