If you wish a fresh water fish to be kept alive and well so that it may be studied or kept as a pet. The fish will need to be placed in a suitable container with suitable water that has suitable parameters. Without water a fish will die just like you would die if your air supply was removed. If the fish was a fresh water fish and the water was salt as opposed to fresh, to the fish, it would be similar to what would happen to you if someone put poisoned gas in your personal air supply. You would be extremely ill and then die. So would the fish.
Explain what would happen if a piece of seaweed from the ocean was placed in a fresh water aquarium?
the marine fish would pretty much suffocate and die. so putting marine fish in fresh water is not a good idea.
They're designed for salt water, not fresh water! Just the way they are made. You can get aquarium salt from your local pet store, but don't put any in there if you have other freshwater fish that don't need it. Or get a tropical freshwater fish like mollies instead!

You can raise a sea urchin in a salt-water aquarium. There are no fresh water sea urchins so you would need a salt-water aquarium to properly care for the urchin.
Nothing...they die....
There is no such thing as a "self cleaning tank(aquarium)" if you are too lazy to clean a tank you should not consider having one.
As a decoration, maybe. As a living entity--NOPE.
