White/red lump on fishs mouth

How do I treat this on my fish

It’s hard to see what your referring to because the picture is so blurry, can you get a clearer one?
What are your parameters? (Ammonia, nitrite, ect)
How long have you had the fish?
Have you added anything new to the tank in the last two weeks?
How often do you do water changes and how much do you change at a time?

Can we have your exact parameters please? It’s easier to tell if something might be wrong with the actual information

White lumps on the mouth of neon tetras is something we are coming across more frequently of late. It seems to be a viral infection affecting neons, so there's no cure. The fish behave normally until the lump gets so big it stops them eating, and which point they should be euthanised.
