I've lost fry because they didn't have enough flow and also because of planaria, mostly a combination of both. Get a HOB
and position your breeder net or trap directly in the flow. Be sure to have a lid with lots of holes in it. If you have a separate fry tank, get something with VERY high flow rated for 2-4 times the tank volume
