Guys, please help! I am getting batches of fry every three and a half weeks but they keep dieing about a week to 10 days after they are free swimming. The last few batches I tried feeding them live baby brine shrimp and frozen baby brine. The fry would swarm the cloud of food but didn't seem to be eating as it appeared the baby brine was too big. They slowly died one by one after a week and a half or so. This batch just started free swimming 2 days ago and I am feeding them frozen rotifers and hikari's first bites. They swarm the cloud of food when I put it in but both the fry and the food are so small along with there being so many fry, it's hard to be certain if they are eating. If this works I will start with the baby brine once they get bigger but I am sick and tired of losing every batch of fry. Please give me some advice, I will try anything.
