freshwater fish provide none of the nutrition that sw fish need to truly thrive, if you have tried the method of shaking a silver side on a stick and he wont take first try to soak that silver side with garlic extreme it helps to induce the appetite. Also if he will only take to silver sides make sure to soak them in some sort of vitamin to give them more nutritional value. I found the best things that my lion ate were scallops and mussels and if he would ever turn his nose up at them use squid, it smells awful, but thats just the reason that the fish are attracted to it
