I do have a sig. I just checked but it's not showing(you don't have a sig... ?)
Will they be the only fish in the tank?
I'd keep a ratio of 2F:1M
some people get the kissing gouramis because they look cute kissing, but in actual fact what they are doing is not so cute. They are fighting, that is how that type of gourami fight. So having two fish always fighting will cause stress and then illness.I would also add a few pairs of "kissers"
