Hi! If I haven't said it before, welcome to FishLore
You have room for a
DG, however, I couldn't recommend one.
There's been quite a few deaths here on the forum from what I suspct to be Dwarf Gourami disease.
I lost 2 myself recently.
Of course, I can't be 100% sure that's the cause of death for these poor fish, I just wanted to be honest in my opinion.
You might want to try a Thick lipped Gourami (Colisa labiosa ) or a Banded Gourami (Colisa fasciata) as they're not suseptable to DG disease.
Good luck what ever you decide
