Pimple on a Clown's mouth

[Shadowsong]

My biggest loach has something like a pimple on her mouth. I think it started about two months ago as a reddish spot. At first I though she just fought with another loach and only observed the spot for infection. For a while nothing happened, so I let her be. Recently I noticed she has this pink lump in the same place the reddish spot was. It doesn't seem to bother her, as she is as hungry and as dominant as ever. Is it something I should be concerned with?

Here is the best picture of her I managed to get:

It could be a cyst (pimple), but to me it looks more like a growth of some sort.

Definitely something to keep an eye on, but I'm not sure what you could do to treat it.

I'm not sure about the reason for this. How is he right now ?

Not sure what to say about this... but if he's fine than you dont have to worry about it too much(Unless it begins to grow really big). I have only one thing to say... that is a giant loach
