Most fish reproduce by the femal laying eggs then the male coming to fertelize them and they protect them until they are born. Now I was wondering if it was possible for a Femal Oscar for lay eggs and a male natural fish such as a sunny or maybe a bass or something to fertelize them. I know that this would be exremley rare if even possible but I was just wondering. And no I am not going to try it lol I was just wondering. Thanks.
