Gourami ID Help

I bought a used tank and 3 Gouramis came with it. I was told they are dwarf Gouramis but they don't look like any dwarf ones I have seen pics of online. The Gold Color one is the bully and has been ramming the other Gouramis and the smaller fish. I want to add tetras and shrimp but think I will have to re-home the Gourami's. Any help IDing the fish would help thank you

 

The first and last ones are opaline gouramis, a colour morph of the three spot gourami. Middle one has the typical pattern of a three spot gourami, maybe a gold gourami. Could you get another photo?

They are definitely Trichopodus trichopterus, which are bigger than dwarf gouramis, so naturally they need more space to stop territory issues.

 

Multiple males of the same species

Yep looks like a gold gourami.

 

2 blue gourami and a gold gourami. All are color varients of the same species, the 3 spot gourami.
