The Blue Gourami (Trichogaster 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. This fish is like the 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 male blue gouramis.
Young Angelfish Harassing Young Opaline Gourami | My Aquarium Club
I have a large male opaline gourami. He's peaceful towards all other fish but won't tolerate another gourami of any kind in the tank with him and chases them relentlessly. So, he's the only gourami in my community tank. From: Epi

The opaline gourami – another blue hybrid, a pale pearl-colored fish.
I just got a new tank, I have about 9 fish in a 10 gallon. One of my Opaline gouramis was always playing in the mirror so I got another. The first day they were chasing each other around a lot. (Not in a violent way) and I believe it's a male that I already had and I just got a female. Everything seemed fine until yesterday, I checked the tank and there was a chunk of tail (or the biggest fin in the back I don't know what it's called lol) of the female and now she stays in the cave. I have a lot and the male tries to hug her but she swims away and is almost never at the surface anymore. Will she heal and what do you think is the cause of this?A couple weeks ago, my family bought some fish. I'm not sure of all the breeds, but their are two gourami fish in there. I have a pearl gourami and there is also a Opaline gourami. I believe the Pearl is a male and I think the Opaline is as well. There is also a guppy in there as well and I'm slightly worried. From what I've read, smaller fish tend not to last with gouramis. Should I be worried for the guppy? Also, the Opaline gourami has some strange behaviour. Whenever we switch the light off in the tank, it goes crazy. It swims to the top incredibly fast and then zooms around for a while. It tends to circle around the thermometer, on the side of the tank, as well. It chases my pearl gourami around constantly. Is there anything wrong?
