Thanks for the update 
It sounds as if you are doing a good job in caring for them, but I would suggest doing a little more research on your gourami, as even though they are smallish labyrinth breathers, they still need space. Male bettas can get away with smaller tanks due to them not always being that active (long fins), but gouramis do have different needs. A 5 gallon should be the very minimal for a single dwarf gourami. Would also make sure the heater is set for 80-82*F, as these guys can be a bit more susceptible to diseases and they do better in the warmer temps. As well as they can grow to be about 3.5 inches, bigger then your average long finned betta..
Don't think I am saying you aren't a good owner, but there are differences in betta and other tropical fish, and why bettas can do good in smaller tanks, and why others shouldn't be. Just want to make sure you are aware of what those guys need. Good luck
