Logan,
We have a dwarf lion in our tank and had one previous to this one. We have had no problem feeding either by just dropping live feeders in and letting him hunt...they always manage to catch their food. We are at an advantage living in Florida as we go out to the beach and net our live feeders for our predators, but with cold weather here, feeders are a bit scarce so we have had to substitute gold fish and small swords etc...but get our ocean feeders as often as we can to keep up the nutrition. We haven't had much luck with feeding frozen food to them. Good Luck and I hope you enjoy yours as much as we do ours. Heres a pic of our little guy. His name is Tigger.
