Well water can be OK for some fish but it can also be deadly. It is always best to check well water out with a complete water testing kit or take a sample to a pet shop to be fully tested properly. Once you know its make up (parameters) you can find out what species of fish it may suit.
If you run it through a DI cartridge you can, I would not use it untreated.
The minerals in it are not the same as what is in sea water.
You are better off using RO/DI and then adding the appropriate salt mix.
Fish can live in well water. They are going to have to have a good supply of food if they are going to be living in a well.
yes you can. allways follow aquarium procedures in adjusting the water to be suitable for the fish you keep.
You have several choices: tap water, water from another tank, Reverse Osmosis or Deionised purified water, softened water, bottled water, rain water, or collected water.
A little testing is in order. Safe for human consumption is not always safe for fish. Most likely, yes. But I'd have it tested for chemicals and metals before using it for tropical fish.
I would use a cleaning tube or use a bowl or something

Add a few sea shells.
No, you should be able to use it
fish tanks
Water tanks are a way for people to have fish in their home so they can they enjoy them. There are also water tanks inside each home that hold water for people to use so they can shower, drink, and wash dishes and clothes.
Best materials are all natural from the environment the fish is from. Porcelains are normally safe and well as plastic, just be cautious of type of paint that may leach into water. Any item should be thoroughly cleansed with hot water. Do not use soap. Diluted vinegar can be used for scrubbing.
Yes you can, but you must make sure you rinse the tank extremely well to get rid of the soap residue so it will not harm the fish. you can also use a mixture of water and vinegar to clean the tank which will clean it but not be harmful for the fish after rinsing.
There are commonly two types of 'regular' table salt. One is 'Iodised' the other is not. Do not use the 'Iodised' salt in fish tanks. I would advise you to use cooking salt as that is not 'Iodised'.
Provided they will not leach sap into the water they should be OK. Otherwise the twigs/branches could poison the fish. Most smart people use live water plants as decore in their fish tanks.
Yes
use when there is a water shortage and use when there is a water surplus
