No! marine fish are salt water fish and tropicals are fresh water fish, this cannot be changed.

No. Not in the traditional definition of the tropical tank. A tropical tank is a freshwater aquarium. Regal Tangs are saltwater fish and go in a saltwater tank (marine aquarium).

Rule of thumb is to not mix tropical fish and goldfish.
No. The temperature variation will kill one or the other. (Too warm for cold water fish, too cold for tropical fish)
Blow fish (Puffer Fish) are tropical, brackish or saltwater fish. Usually found in the more salty parts of estuaries. In captivity they are regarded and treated as "Marine Fish". Setting up a marine tank is a very complicated business and involves the use of technical equipment like Protein Skimmers, Ozoneizers and the like. Maybe you should ask your question in the marine section.
U buy tropical fish and get a background and then that is how u can do that
They can be in a community of other tropical fish of the same size.
no tropical fish need warm water
Angel fish are semi aggressive fish. They may have a tendancy to pick on the gold fish. Also, angelfish need tropical warm water to survive. Gold fish like cold water. I would not put them together. If the Angel is big enough it will eat your goldfish.
Room Temperature (*does not matter as long as you don't throw ice cubes in the tank or heat it up on the stove) But when you purchase them with the bag containing them, do not immediate throw them into your tank; instead, put the bag with the fishes into the tank (filled) and so they can gradually adjust to the temperature in your tank. Seriously, people makes this too complicated sometimes. They are fish, really easy to take care of. I have gold fish and I have never bothered with the temperature, they are healthy and lived more or less to their life expectancy.
The Violet Gobi is a brackish water fish (almost marine), and the Kissing Gourami is a tropical fresh water fish. They each need completely different water conditions and parameters. The conditions that would suit one, would kill the other.
