^ Same.
Using a mortar and pestle to just crush up pellets that the parents are eating has worked great for me.
For really small fry I’ll even soak it in some tank water and use a dropper to add the food to the tank. Once they are a bit bigger I just sprinkle it in the tank.
Depends how young they are, to start I used infusoria, but then moved to daphnia, baby brine, and then vinegar eels. At that point, they could eat regular food
We start feeding them crushed up flake at 3 weeks of age. We only feed the BBS at mid day feedings so they are hungry that night and in the morning. The are usually transitioned to crushed flakes from BBS completely by 4.5- 5 weeks.
I had a small food processor dedicated to fry food.
I would mix pellets, thawed peas, algae, with tank water, puree it, and feed to fry throughout the day, even add newly hatched brine shrimp to the mix (after it was puered) doing maybe 5 or 6 feedings per day, pipetting it into the shoal of fry, and would also allow algae for grazing to grow on anything in the tank.
