I have a jd and an oscar in my pond and for the last few days they have both been huddled up together around a rock and been very territorial ( even bit my dog when he stuck his nose in the water) i can make out what i believe to be a few eggs and they are fertilized. I didn't think oscars could cross breed so how is this possible? the eggs are fertilized and definitely theirs so should i expect some little mutant hybrid fish or will they probably not hatch.
