Sunfish specific food. The guys that make it were concentrating on the aquaculture industry for a long time, and are good at it. They will do necropsies, blood tests and other testing on fish to determine what to add or remove on the fish food to make it as efficient as possible. Less food going out the south end of the fish means better water quality and more efficient food conversion by the fish.
Matt got them to look into the pond industry. For Aquaculture they make food that is fish species specific, and this food is sunfish specific. I'm working on getting a bag of Largemouth specific food.
The biggest thing is working out the distribution system, i.e. shipping.
The pellets aren't "pellets", they look more like worms. The food works in Texas Hunter, Stren AquaPro and Diamond feeders - I've tried it in all 3. Sunfish that aren't pellet trained seem to train easier on this food. But, because of the weird pellet shape, pellet trained fish have to learn all over again - they don't recognize it as "food". Catmandoo said he has RES eating it.
Tony, I told you that your fish were weird!!!
