i would be very surprised if there was not one possible disease or infection that would tranfer from crickets to fish, including oscars. it may not be common and all the mods on oscarfish may not have had a problem, but that doesnt make it fact. i know what you mean about the oscarfish mods. they have a vendetta against carbon that i am trying to load up ammo for to go back at them. forums are for sharing your experiences, mine contradict yours and yours contradict mine but we are both right because it did happen to each of us.
