B BUG
This past summer I bought 100 tilapia fingerlings, labeled as "fry" from the hatchery. They were 1/2" to 3/4" long.
To feed them I blenderized dry Optimal BG, as I had no finely processed feed from that manufacturer.
The fish seemed to take to the powder well, grew rapidly, and are eating partially crushed BG now.
Possibly the higher nutrient value of the proper Optimal fingerling sized feed would give even better results. All this was just part of an experiment to raise some aquarium tilapia.
