It's rare for wild types to have more then a faint yellowy dorsal (males) in stores, as they lose their colour under stress. If they held those colours in stores, they would be beyond popular. They're the classic example of the prize that awaits those who do their homework.
I haven't seen the mutated forms in a home aquarium, so I can't be sure. You may have males if there were grey ones too - females are largely colourless in the natural forms. Small gouramis have become real subjects for linebreeding, and a lot of mutant forms have hit the market over the past 20 years. The little Trichogasters are mixed, spliced, and modified, and that's probably why no one is answering.
Odds are, they'll be peaceful, as the honey gourami character should shine through. I often had groups of males, as my breeding always gave me a surplus of males, for a reason I couldn't sort out. They were fine together. Two is always a dangerous number though, and if they do squabble, they'll target each other. They don't look like hybrids, so you should be okay. It'll be interesting to see how they colour up. The body shape's good, and maybe they'll turn out to be the real thing.
