i feed my fish night crawlers that i get from outside since i love the outdoors and am big on fishing and hunting, anyway there are NO chemicals or pesticides around my yard. would it be safe to feed my fish worms like 1 time every 2 days or even more. i only feed them about 5 to all my fish. i still also feed them their regular food after the worms, just not as much. my oscars will eat them, as will my cons, jd, firemouth, and my barb looooooves them. so how often can i feed them worms. i do not feed them feeders, im trying to get guppies soon, i do not want to take the risk of a disease. thnx.
