antwon,
don't be so "desperate"...a healthy lion can go a few weeks without a meal. these fish are binge/fast feeders, which means they eat a meal then wait for it to digest, and then eat again.
if you can't find ghosties, get some guppies, mollies, or platies for the short term. just try to steer clear of carp (goldfish, rosy reds), esp. if they're too large for the fish.
