To determine the type of water to use in your aquarium first decide which fish and livestock you want to keep. Most people start with a freshwater aquarium housing community fish. The water used to set up this type of aquarium is usually drawn from a sink in your home which is normally either municipal or well water. Municipal water typically contains chlorine or chloramines that must be removed or neutralized before fish can be added. Water conditioners are available from pet and aquarium stores. Well water should work straight from the sink but it may be best to take a sample of water to an aquarium store for testing.
If you would like to set up a Saltwater Fish aquarium you can use municipal water, water drawn from a well, or filtered water such as reverse osmosis or reverse osmosis with deionization. When setting up reef aquariums with saltwater fish, invertebrates, and corals, most hobbyists use filtered water because impurities such as phosphates and nitrates which are food for nuisance algae have been removed.
The type of water in an aquarium does not affect how thick the glass should be. Glass thickness is determined by tank size; and heavily influenced by height.
The temperature of the water depends on the type of life/fish you intend to keep in the aquarium.
Aquarium water should never be hot; depending on the type of fish you keep, the temperature will vary.Goldfish for example are best in 75F, but a betta prefers 80F. Do plenty of research about the fish you are considering for your tank before going out & buying anything.

Anything labeled safe for aquarium use. Beyond that, it depends on what type of fish you are keeping, and whether or not you have plants, for which type of aquarium substrate (gravel or other lining for the bottom) should be used.

The best type of plant to put in an aquarium is going to be dictated by the type of fish, temperature of water being used, the type of food, and the aesthetic preference you desire in the end product of the aquarium.Going to your local aquarium store and looking at options with someone specifically knowledgeable on the topic would probably be a good investment of time and energy.
Good choices would be a pea puffer, spotted puffer, or a figure 8 puffer
A ninja can have an underwater adventure in an aquarium. He can search the castle in the water and try to find out what is in the treasure chest. He can swim with the fishes also.
The nasturtium plant can be placed in an aquarium, but it most likely will not survive very long. This type of plant does not do well completely immersed in water.
Seahorses are salt water and frogs are fresh water, there are special aquariums for salt water fish type creatures.
An aquarium, if you want plants, depending on the type you may need substrate, a filter, sand or gravel about 1 pound per gallon, a light between 5000K and 6500K (it does not have to say aquarium), water purifier, water, fish food, a power strip that has at least 4 outlets, an aquarium heater if you are going to have tropical fish. and about 30 minutes to put everything together and add water
