One of my gold gourami has seemed to die for no reason at all. I think that the water is fine because my catfish have had no problems or my knifefish. They are the most sensitive ones that I own.
The tankmates are overlooked. What species are these catfish and knifefish? It is possible someone is bullying the gourami by harassing it around even if the bully doesn't leave physical injuries to the fish.

What are your water parameters?
What size is the tank?
What do you feed and how often?
What is your tank maintenance regimen?
 
Ok so there are four trays for media. The top one is a floss pad, I put in a new one. The next had another floss pad, changed it as well. The next one had a flooss pad, and carbon sack, changed both(rinsed corbon before hand). Last one has a coarse media pad pad (which serves as bio filtration) and a floss pad. Only the floss got changed.
 
The tankemates are 1 featherfin knife, 1 rope fish, 2 pictus, 2 tinfoils, 1 sunfish, 1 angel, 1 striped raphael, 1 senegal bichir, and a common plec also of corse another gold gourami which is fine. The only fish that ever chased/ harred was the sunfish. But only if in his hunting zone.
The size are 48"x25"x18" with plenty of shelter for ampel hiding. I do 1/3 water change every 3-4 weeks. The water paramerters are...
-Copper 0.0
-Amonia 0.0
-Nitrite 0.25
-pH 6.0
I feed them twice a day, once before school and once before bed.
Morning food consists of cichlide pellets (for the sunfish and whom ever else can eat), tropical flakes, dried blood worms, and shrimp pellts.
Night feeding is one cube of beefheart, and one cube of freshwater vireity (either bloodworms, chichlid chow, emerald entree, or spirulina-enahnced brine shrimp) pluss a few flakes, some shrimp pellets, and one algae wafer.
 
idk it was barely over 8 months old
 
How about your nitrate? Nitrite and improper water changes are the issues. It should remain zero and with a bioload like that, you should be performing at least weekly water changes. The changes every 3-4 weeks is too tremendous even for a gourami. This is the likeliest culprit of its death. Other possible culprits are the sunfish, your other gold gourami, knife and possibly tinfoil barbs. How big are your tinfoil barbs?
 
about 6" it was about 4" sunfish is about 6.5" and the knife is about 8", and my testing kit has no nitrate testing, when i work tomarrow i will pick up one that does
 
Frankly, your tank is overstocked already, let alone inappropriately stocked. If by featherfin knifefish, you mean the clown knives, then I'm sorry but these are absolutely too big for your tank. Not only that, they are more aggressive and I would not be surprised if it starts bullying all your other fish. You need to correct your stocklist.
 
o hell no, i know that, it is an african brown almost full size
