you dont
Tropical and brackish are not mutually exclusive. Tropical means warm, and brackish means somewhat salty. Many brackish fish ARE tropical, and many tropical fish are brackish. You can keep tropical brackish fish with other tropical brackish fish, if they have the same temperment and will not harm or eat eachother. You can keep some brackish fish with some freshwater tropicals, and similarly you can keep some brackish fish with some marine tropicals. There are no wide open set of principles for brackish fish compatability beyond those that I have just illustrated.

It depends on what type of tropical fish you are intending to keep; it ranges from 6 (freshwater & discus) to 8.5 (for cichlids).
Rule of thumb is to not mix tropical fish and goldfish.
it is a tropical fish and like most tropical fish they all eat tropical fish flakes and to keep it strong and help it grow faster i recommend you get frozen blood worms and a heater also helps and you spelled goby wrong.
It depend on what kind of fish gold fish like it cooler and tropical fish like it warmer i keep mine at 75 degrees and they love it
The correct temperature for tropical fish is 72 to 80 degrees. I keep mine at a constant 75 degrees with a heater designed for aquariums.
Its probably from the filter you are using, and probably from the natural fish oils.
No, catfish is not a tropical fish.
Yes, it is bad to put tropical fish in with river fish. The river fish can make the tropical fish sick.
Concientiously. I research the species I wish to keep and then provide all the requirements the specific fish needs to thrive.
Yes, a siclet is a tropical fish
