I have a 10G tank with about 15 3 day old goldfish fry in it. The male is again chasing the mom and I see a new batch of eggs in the main tank. Can these be added to the ones I already have or will the first batch eat the new ones? I also don't want to bring any fungus in from the new eggs and hurt the original batch. Has anyone ever added more eggs before or should I just let Mother Nature take her course with the new batch?
