Thanks for posting. Will be interesting to see results with the "meat pie" formula with large fish. I would think a lot of it would scatter all over the tank once they hit it. Even if you turn your filters off during feeding (which is a pain with my 225 that has a sump), it's still in the tank. Unless you have some smaller fish or bottom dwellers to clean it up(usually not possible with really aggressive species), that's going to really add to your bioload.
