mouth rot?

[dead_letters]

ive noticed that my female betta has a funny shaped mouth and its only been like it these past weeks.it looks really lumpy like shes growing stuff from her mouth or shes trapped it and theres sum loose skin.Ive never noticed bfore.Is she supposed to be like that or could it be some kind of mouth rot.I cant really take pics because shes really tiny for the camera to get a clear pic.

what colour is it? does it seem to be spreading at all? is she behaving normally? is she eating well? what are your water parameters?

Shes a purple/pink colour.The stuff on her mouth is the same colour as her.I dont think its spreading because i have 3 platys in the tank with her and they seem to be fine.I think shes behaving normally.She sits still in the weed alot though.Shes eating fine too.It just looks like shes tried to eat something too big and her mouths stretched but i dont want it turning into something more serious.

Any chance you could post a picture for us?

Edit: here is a pic of a betta with a normal mouth, it might help
