we have a dwarf gourami that began loosing weight a few days ago. I noted yesterday he was eating but could only take small bites. Today there is a small growth on the side of his mouth. It is not red. It looks like a little tumor. Not sure how to help this guy or what it is. Any thoughts? Thank you!

Hi and welcome to the forum 
Can you post a picture of the fish?
If the website says the image is too big, set the camera resolution to the lowest setting and take some more pictures. Post 1 or 2 images that clearly show the problem.
-----------------------
How long has the tank been set up for?
How often do you do water changes and how much water do you change?
Do you gravel clean the substrate when you do a water change?
How often do you clean the filter?
How long have you had the fish for?
What new fish have you added in the last 2 weeks?
-----------------------
Dwarf Gouramis (Trichogaster lalius) and all their colour varieties carry 2 main diseases, Tuberculosis (TB) and the Iridovirus. I don't think this is TB.
The Iridovirus is a stress virus that causes sores on the body when the virus becomes active. There is no cure for this disease but if you keep the tank clean (do a 75% water change and grave clean the substrate each day for a couple of weeks), clean the filter, keep the water temperature around 26-27C, and feed the fish a variety of foods, sometimes they survive it. You can add fish vitamins to the food. However, the virus will always be in the tank and fish and will become active whenever the fish gets run down or stressed out.
