A swordtail is a tropical fish and a goldfish is not. The swordtail would need a higher temp. than the goldfish. Depending on where you live it probably wouldn't survive the winter.
Out of all the different varieties of goldfish the top pond goldfish would be the koi, the top goldfish probably of all time would be the common goldfish, and the top fancy goldfish would be the Oranda. The second most common pond goldfish would probably be the Comet, the second for the common varieties of goldfish would be the Fantail, and the second most popular fancy goldfish would be the ryukin. The third most common pond goldfish would be the Shubunkin, the third for the common goldfish varieties would be the black moor(although this technically counts as "fancy"), and the third for the fancy goldfish would probably be the Celestial and the Ranchu.To make this data more clear I've organized it into a list:1. Common goldfish2. Koi3. Oranda4. Fantail5. Comet6. Ryukin7. Black Moor8. Shubunkin9. Celestial10. Ranchu

The goldfish will eat the mosquito's larvae before they can leave the pond and fly.
Well, common goldfish can either live in a pond or home aquarium, its hard to answer precisely what you are asking because goldfish are not wild fish and don't really belong to a natural ecosystem.
This is a literature question not a goldfish one.
no the goldfish would it the tadpole
Algae in a goldfish pond is quite common with an increase in sun (light) and temperature. To try and keep algae to a minimum you will want to look at ways to provide the pond with shade, and regularly change out some of the water for fresh water during the warmer months.
Get a separate tank for the goldfish (or swordtail either or) these fish are naturally not compatible and putting them together endangers the lives and overall well-being of both fish. If you keep them together much longer the goldfish will probably be wounded by the swordtail, get an infection, and die. Hope this helps

Year round, but especially in Spring for pond goldfish.
Goldfish can survive in a pond without a pump, but it is important to ensure that the pond has enough oxygen and is properly maintained to support their health and well-being.
