You should never put any terrestrial flower in water that has live fish in it you will poison the fish. If you want to put a plant in a fish tank or bowl, then the type of plant depends on the type of fish that you have (Which was not specified in the question). Marine fish can have many types of algae. Freshwater tropicals use various forms of tropical aquatic weed. For coldwater fish such as Koi there are flowering plants which can be used in ponds safely.
no
The freshwater plants you have taken from the shop and put directly in your tank may be dying out due to the water being too cold, too warm, getting too much or too little sunlight, or too much or too little oxygen in the water. There are many things a plant needs to survive.
No betta fish cannot survive with a calla lily because the plant is basically poisoning the fish

I think your answer is simple everybody knows that fish hate dancing there more of a singing animal.
One time I came home and my fish had jumped out of his tank. I put him back and the next day he did it again! I took that as a sign he wanted to die.
Some fish live in salt water because they just do. Some fish live in water because they were put in water. If you get a fish at home you can put it in salt or water. It also depends on there skin because the fish can have very sensitive skin and can only touch a certain kind of water
no. they live in mud.
