Too late, I already purchased it.😆 Unfortunately the study fed baby brine shrimp for the first week or so and then transitioned to the commercial diet, so does not help me with day 1 feeding. There was also no mention of brands of commercial feed, but nutrition analysis was provided for each food tested. Looks like the one that performed the best had 54% crude protein and almost 19% lipids. There was some reference to particle size but, again, not really relevant for day 1.
This article has the most detail of bluegill fry zooplankton preference and would seem to suggest a particle size of 100-200 micron would be best. I bet the aquamax is not going to come close to being that small, but I am considering buying a lab sieve to filter down to that size(and do more grinding if needed).
Here is the article:
