Yes, it is possible if the betta lives with other bettas in a heavily planted pond, I would heat it if you live in the Northern states. Never have normal pond fish live with a betta.
Yes they can live in bottled water but not tap water unless you treat it with dechlorination drops.
no a Betta can not live in a pond because it has to have a steady temp or it will go into shock and die.
Guppies are tropical fish and should not be kept any colder than 65F. If your outside temperatures don't go below that then your guppies should be OK outside,
yes, i put sunfish in a 40-60 gallon tank and they did fine. They like to eat worms.
They'll eat leftover fish food.

Put pond water in a cooler with fish in it. Then bring it to the other pond and put small amounts of the new water into the cooler so it slowly adjusts to the environment. After about 20 or 30 minutes of doing this, take the fish out of the cooler and put them into their new home.
Pondweed can be placed in a tank to create a pleasant scene, or to add extra oxygen to the water. The downside is that the pondweed could introduce fish diseases or water snails to the tank. Always use a special sterilising solution on the pondweed before introducing to the tank.
goldfish, koi
It is a more natural environment for them.
Gold is an inert metal (not dangerous to fish). You can put it into a fish tank if you choose too.
No.
put it in your backyard or a pond
That depends on if you fit the fish to the tank, or fit the tank to the fish. Koi will grow to the size of the tank. The bigger the tank, the bigger they will grow. You can put about 6 4 inch Koi in a 30 gallon tank. And of course, the bigger the fish, you need to adjust your tank size. The koi will quickly outgrow your tank! They will be like prisoners in a cell, not able to move around. Probably enough to survive if you keep up the waterchanges, but not enough to thrive. Koi belong in a pond.
