IMO until recently, pond owners feeding pellets were more interested in achieving high relative weights rather than the health and life span of their fish. As this thinking slowly changes to looking for both growth and health, I think we can look for companies like Optima to lead the way to the future as fish chow is their main product line. We are small potatoes to the huge livestock and pet food chow producers.
Just my 1 cent
With dogs, slow growth is desired when raising a puppy so a moderate food is usually best. If the diet is adequate during growth the final adult size will be the same as if a "hot" food is fed with faster growth. The final result in either case is determined by genetics not food but the slower growing puppy is usually a healthier specimen orthopedically. Don't know if this can be applied in any way to fish, lol.
