Crossband Chocolate Gouramis and Female Betta?

Hello all,

I have a 15g tank with a female Mahachaiensis betta fish and some cherry barbs. I'm considering shifting the stocking to the following:

1 female Mahachai
5 Crossband Chocolate Gouramis
7 chili rasboras

My real question is, would crossbands be ok with the betta? She's pretty chill usually. If not I'd keep the cherry barbs and just add some chilis.

You can try it out and see how it goes. But generally, you dont mix labrynth fish species, I would not risk it, even if the seem to be getting along you can not see all the simptoms of stress in animals, You may find out too late that the fish are squabbling at night, when they should be relaxing.

I don't really have a backup plan as a backup, but does anyone know how it might go? Both are a little pricey (especially when there's 5 chocolates) so I don't really want to risk it if it might not work
