I have a a 55 gal tank with 2 lavender, 2 gold, 1 blue, 1 dwarf cobalt gouramis along with a few other fish but my main question is are any of these dangerous to each other? The gold's are a male and female which chase each other a lot but then almost like cuddly with each other so thats normal I assume. But the blue is the one I'm concerned with he seems to chase everyone I'm just wanting to make sure he will not kill the other gouramis?
Is This Normal For Gouramis?

Well could it be the blue gourami that is being more aggressive because he's by himself? I know lavender gouramis are basically the same but different color but maybe removing the blue gourami from the tank could lessen the aggression?
Well should of went more into detail my buddy had to scrap his tank so that is where I got the blue gourami and gold gouramis from. I was under impression from what I read that most gouramis could get along but it really only seems to be the blue gourami that is being the main aggressor to everyone hence why I'm thinking of rehoming him to my lfs. The other gouramis in the tank will sometimes just chase after the other one of their species (gold pair, lavender pair)
Hi Bigd5482 
Your lavender, gold, and blue gouramis (if they are standard size and not dwarfs)are all the same species, Trichogaster trichopterus. The color doesn't matter. Among this species some of the males do tend to be aggressive, not only toward each other, but sometimes toward the females and even other fish in the tank. Evidently that male is the dominant one and he is protecting his territory. You might try rearranging the tank or planting heavily, but it is possible that nothing can be done to stop him.
While this fish might not actually cause physical damage, it could make for very stressful conditions for his tankmates. This will tend to weaken their immune systems and make them more apt to get bacterial infections. If your other fish seem to be overly stressed by his actions, it would be best to rehome him to another tank or to a different owner.

Well I have confirmed the Blue Opaline gourami is a male and one of the lavender ones is a male and the other lavender is a female. They seem to be laying off each other more but I'm curious since both these are Opaline gouramis could the blue breed with the lavender female?
No, meguro, it's the same species that has been line bred for color. Platinum is another color variation of the Trichogaster trichopterus. Neither of these is so well established that you sometimes find ones that are much more attractive than others.
Since they are just color variations of the same species, they can and do interbreed together.
