Oh I think they will. Remember these are anabantids, same family as bettas. In my 50gal I have a male and 2 female golds. All three of them squabble and lip lock especially during feeding time. No real damage in 6months they were doing this though. I imagine it will be much worse with 2 males, especially upon reaching maturity. But, it still depends on the personality of the individual fish, you might win the lottery and be the lucky one..
One will soon rip other fin off a bit but they will run for a life...I rather Separated them .Never put different kind of Gourami in same tank...

I'd check with whomever you bought him from and see if they'll take him back. They might if you give him to them for free. That's better than one getting killed in my book...
Okay, -in this OP's case, would removing all the females decrease the male aggression toward each other? It works with Cichlids...Up front: I'm sorry about your loss. Below info has nothing to do with your situation anymore but since there are many people tossing anecdotes back and forth...
There is too much disinformation about gourami floating about. For any one reading this thread for info...
There are a few anabantoids notorious for aggression. Unfortunately these happen to be some of the most popular ones in the trade, leading to all anabantoids having the reputation of murderous fish not fit for communities or groups of their own species. This is simply untrue.
The most notoriously aggressive labyrinth fish are definitely captive-bred betta splendens and paradise fish, that generally cannot be kept together without serious or even fatal consequences. Wild betta species are usually much more tolerant of each other and plenty of them can be kept in a harem style without issues - however aggression levels differ per species and I don't know enough about them to make a judgment.
Among the gourami, dwarfs, kissing gourami and three-spot gourami (often called by their colour strains "blue", "marble", "golden" and "opaline") have the worst reputations. For all of these, there is no guarantee that any individual fish or combination of a few individuals will show aggression, or that the aggression will be of a serious nature. But the risk is very present and dwarfs, for instance, or known to kill each other on occassion. Three-spot gourami are also known to make live unlivable for each other in tanks.
Pearls can also show similar aggression, but seemingly at a lesser rate (as in, buying 5 random fish of each of these species, the best odds of having a group without aggression issues would be the pearls). This doesn't mean that there aren't enough anecdotes out there of even these fish not being able to live together.
Moonlight, thick-lipped, snakeskin and banded gourami have a much softer reputation, reports on sparkling gourami differs between this level of peaceful or more risky like Pearls.
Honey gourami have the best reputation as a peaceful fish, where sparring between males never comes to actual blows.
(I am excluding the peat swamp species because reports are either conflicting or scarce due to their difficulty of keeping, anyone interested in them should do some thorough research and come to their own conclusion)
Not with three spots. Those things will fight regardless of a female's presence or absence. In fact a male and female (or female-female for that matter) three spot pair can fight as savagely as two males would. It boils down to individual personality, as there are certainly exceptions, as with most other fish.
I'm talking about this OP. Could removing all his females decrease aggression between his male blue and golden Gourami? PascalKrypt?Not with three spots.

OP has one blue and one gold male. he hasn't any females..
As was pointed out, it doesn't apply to this case.
