I didn't know goldfish were carnivores. But this guy swam around for a good 5 minutes or better slurping this worm in and out til he finally bit it in half. Damn worm was 2 inches longer than him and he's still telling me he's hungry.
I was amazed watching my bichir eat a worm longer than he was. Wonder if he would go after a snail? My buddy has a bunch of clown loaches and it is like crack to them.
