Goldfish usually spawn in ponds/lakes/rivers during the spring after the cold winter weather has cleared up and the goldfish have put on some weight, most varieties of goldfish have to be around 4-5years old to be mature enough to spawn successfully and they lay their eggs in densely planted area's. Successfull breeding is unlikely to happen in the aquarium between goldfish due to;
a. They sometimes eat each others eggs if they can find them after spawning, in an aquarium this usually means they don't have far to look to find eggs to eat.
b. They need planted areas to lay their eggs in, but goldfish also eat plants, so most goldfish tanks are not planted.
c. They need the right water quality/temp conditions to mimic the conditions in the wild that would usually encourage spawning, in the average aquarium these conditions are unlikely to happen.

edit: the bubbles in the goldfish poop you found are most likely bubbles caused by gases building up in the poop as it decomposes.

ibat46, i remeber the first time i found one of those poop things in my tank... i was pretty confused too lol! But like Tokis-Phoenix said, it is most likely to happen outside where the nature works its magic on them.

Goldfish eggs are about 3(?)mm in diameter (it's been several months since mine last layed any (that I happened to be around to see, anyway), so I'm not 100% sure on the precise size) and white-ish. They are separate from each other, but are a bit sticky, so they'll stick to plants and other surfaces (including tank walls), and may clump together.

It is entirely possible to breed goldfish successfully in a tank, however, the chances are a bit higher in a pond. Eggs in a tank won't last long if they're left with the fish.

I agree that the bubble-filled strand is most likely a gassy poop. Do you surface feed your fish? If the fish is taking in a lot of air when it feeds, it's possible for it to travel through the intestine and come out in the poop. Clear, stringy poop may also be a sign of internal bacterial infection. In any case, bubbles are not a good sign.
