More practical.
Get a freshwater crayfish. They are smaller, and can live in normal freshwater, cold or tropical depending on the species.
They need a normal filtered fish tank, but a 10gal tank with a freshwater cray is perfectly practical, compared to a 200gal marine tank anyway.
Yes it is possible but you would need to create a copy of its natural living environment. Coral and other fish would be a good idea.
