Seriously, you're not supposed to feed meat like that to fish. Earthworms from the fishing dept at WalMart are cheap, crickets are cheap, mussel and shrimp from the grocery store would last a long long time, june bugs, that sort of stuff. I mean, you can do what you want, it's your fish. You'd be amazed at how fast they grow and how healthy they are if fed the stuff I mentioned. One of the biggest factors in how fast fish grow is how low their nitrates are. Why do you think breeders change the water 100% every day in their fry grow-out tanks? They feed a lot and change a lot of water to get those babies growing.
