Red Spots On Otto

[Aveena]

hey, i have 4 ottos in my tank and have recently noticed one of them is quite a bit bigger than the others, and has 4 red spots near his/her mouth/nose...
all my other fish seem to be ok. Also this otto looks alot paler than the other 3, but is still swimming and eating well. And the spots look slightly raised.
At the moment.
Could someone please help me, as i dont know what they are, and if theres a treatment for it.

Its sounds bacterial so I would treat with a bacterial med.
