In other news, I purchased a few lbs of aquamax fry powder on ebay yesterday. I also contacted Purina to see if they have any information on particle sizes as nothing is listed on their site.
Try Optimal fish food.
Optimal Starters come in a range of sizes to fit your needs.
• Starter #0 is a powder designed for the first feeding of tiny fry. This line is useful for those who hatch their own fish.
• Starter #1 is a crumble line for fish that are too big for a powder yet still under half an inch.
• Starter #2 is a 1.5mm pellet and designed for fish in the 1-2″ range.
• Starter #3 is a 2mm pellet and designed for fish in the 2-3″ ranges.
• Starter #4 is a 2.5mm pellet and designed for fish in the 3-4” ranges.
Every species of fish has a slightly different mouth size and feeding challenges. The goal is to try to feed the largest pellet size your fish can eat.
For use in the first feeding of newly hatched fish. To minimize impacts on water quality, feed as much food in ten minutes as fish will consume. Feeding at the same time every day is suggested. For more feeding information and tips, visit optimalfishfood.com/feeding-tips.
