The Blue Gourami (Trichopodus trichopterus) is also referred to as the Three Spot Gourami and sometimes even the Opaline Gourami. This gourami is called the three spot because of the three spots on its body. The first two are visible (one on the middle of the body and one near the caudal fin) and the third spot is the eye.

Blue Gourami Opaline Gourami


This fish is like the Betta Splendens in that it needs access to the water surface for using its specialized labyrinth organ in case of low oxygen levels. They can become aggressive and territorial with other tank mates and may be even more aggressive with other males.

Once acclimated to your tank, they can be fairly hardy and can grow to a size of 6 inches (15 cm).

Even though many of the available Blue Gouramis are tank raised it's always a good idea to keep any new fish in a quarantine tank for a few weeks for monitoring before introducing them into your main tank.

The Blue Gourami will accept smaller fish food including flakes, frozen, freeze dried and live foods.

Blue Gourami Comments and Tips

From: Tom
I recently bought some three spot gouramis in both the blue and gold colors. I think these are great fish to have. I work in the fish department at a local pet store and recommend gouramis to people that want a bigger fish that's not too aggresive. This is a great site. Keep up the good work.

From: Nick
These are very cool fish. When I bought it at the pet store I actually asked for a different guorami but the guy put one of these in the bag and I ended up keeping it. As far as I can tell it is a relatively peaceful fish, only getting aggresive towards the smaller fish during feeding times.

From: PaleolithNick
Be aware that it's not only the males which can be aggressive. We recently had to move a (non-spawning) female into a separate tank by herself because she was aggresive to a smaller male blue in the same tank. The aggression was especially *but not exclusively* seen during around feeding times.

From: Scotti
I have four female opaline gouramis in my tropical community tank. My tank consists of Gouramis, Platys, Bleeding Heart Tetras, Balloon Molly, Pleco, and two guppys. I purchased the gouramis 15 months ago when they were babies, as well as the majority of fish within the same time frame. Because most of the fish have grown up together, there are no problems with the gouramis even at feeding time! However, I think thats because I feed them twice a day, the same time every day, and the fish rely on consistency. They all eat well, but not so much that they over eat or pollute the tank with residual food. I put a little food in at a time for about two minutes to prevent waste by just dumping it in. Happy fishing!

Blue gouramis are fun fish to have. They stay mostly at the mid to upper range of the tank. They become very trusting of their owner. Mine would eat out my hand. The most unique thing about these gouramis are their "feelers". They use them like hands to search out things in the tank. They can be a little aggressive to each other but mine were pretty calm.

From: Stephen
They say that the blue gouramis are semi-aggressive, well mine is anything but aggressive. Mine is so peaceful and it is the shyest fish in the tank. All it does is hide behind my rock. So I guess it only depends on each fish's own personality.

From: Pete
This is a very hardy fish and I would recommend it to anyone who is starting out in this hobby. Mine has moved several times and is still very healthy. I have had mine now for about two years and he is about 5 inches long. He can get quite aggressive, especially when it is feeding time with other tank mates so I ended up putting him in another tank. He even went after my Blood Parrot Cichlid. For some reason he does not seem to mind dither fish such Danios or Tetras. In the two years that I have had this fish he never went after the really small fish. Overall a very good and hardy fish for your aquarium. This fish would most likely do better with fish it's own size or bigger.

Best to keep only one Kissing Gourami per tank because they will pester smaller Kissing Gouramis. The kissing action is actually an act of aggression.
