While it's possible that many types of fish may appear to get along, they are not compatible. Goldfish and gouramis should not be housed in the same tank as their needs are different. Goldfish are best living with goldfish.
Gouramis aren't really great fish to have together unless they have room to move around (e.g. at least 5 gallons per fish). Your tank is MUCH too small to have two gouramis, they're fighting for territory. If you don't want to return one to the fish store, then you should definitly just get a bigger tank. Unless you have dwarf gouramis, you should have them in at least 20 gallons. It also depends on what kind of gouramis you have. Some are more social and are more likely to school (dwarf gouramis, pearl gouramis) whereas others prefer to be top dog (opaline gouramis, blue gouramis). Good luck!
no. fish can only mate with fish of the same species. Gouramis mate with gouramis and platys mate with platys.
The best candidates are Betta fish and Paradise Gouramis
Labyrinth fish such as gouramis and betas.
I have a blue gourami with my gold
I have 4 green spotted puffer fish living with a albino tiger Oscar them seem to get along fine, the puffers seem to do there thing while the Oscar tends to himself.
no
Oscar is a type of fish so he is a Oscar fish
Not necessarily. A Betta is a "Labyrinth fish" but all Labyrinth fish are not Bettas. All the Gouramis are Labyrinth fish too.

Yes, keep in mind seahorses are one of the most timid sea creatures.
