yes all fish mate
no. fish can only mate with fish of the same species. Gouramis mate with gouramis and platys mate with platys.
Do you mean will they mate with other fish or get along with other fish? They will not mate with other fish, but they will get along without tetras.
of course, why not?
No.
Oscars are the breed of fish that mate the most. However, guppies and trigger fish also mate much more than other breeds of fish.
they mate at the age of nine months
No.
