It sounds like too much food but two earth worms for a 17 inch eel is not that much.Eels do breath faster then most fish.I stopped giving my fire eel worms all together as i would notice more rapid breathing and the laying on there side.Perhaps worms are hard for them to digest?I had rays in with my eel and he would try to get every worm when i fed them all,sometimes eating 30 night crawlers..He now eats 5 jumbo shrimp every night but my eel is over 3 feet and massive around.I never see him breath harder after eating any more.
