Just an observation, i have smb fingerlings of the same size and age class in 2 different ponds. One pond has very high numbers and the other has around 10% of numbers of fish. I have to feed floating pellets to the pond with low numbers to reduce feed waste because those fish feed slow. because the sinking pellets end up on the bottom. In the pond with high numbers they are extremly agressive so i can use a sinking pellet which seems to be much easier to get them feed trainned. Both ponds were started on sinking. Both seem to prefer the sinking. I prefer the floating to make sure im not overfeeding or creating a bloom or poor water quality. Pretty crazy to see the differents in agressiveness.
