I had a spawn and I'm at 21 days (3 weeks) since eggs were laid. I've basically bucked the advised methods which failed me for the first half dozen spawns. I left the eggs with the parents, until freeswimming for a week, and then I removed the parents from the tank and left the fry. No, Anti fungals, or removing eggs, or evern white eggs this time.
I think I'm doing well. Anyways, my question is, "when do I move the fry to grow out tanks?" I'm doing 20% water change daily, I feed 4x a day with hikari first bites, the fry eat it without issue and are growing. I do vacuum the bottom of the tank, but I'm not that die hard on it if it means sucking up fish, I do the water changes and figure that removes dissolved solids, and detritus isn't all that bad if water quality is good.
I don't make money off the video at all on youtube, it's just for illustration purposes if you want to see the quantity and development stage, only way I know to share a video file easily.
So, any information you have on when to transition to a grow out would be helpful. I had thought to just remove them a bit at a time as growth rates are different, remove the bigger ones to the grow out and let the smaller ones have more time, but not sure if this is right.
