Large Texas Green (halp!)

[peachlids]

My large texas green cichlid has been less active, hiding in my back plants and caves, when usually he/she plays with my dog and will have staring contests with me.
noticed a couple days ago his mouth started to get almost fever blister-like spots on his lips and im honestly scared his mouth might fall off but my tank is in check, my other fish are fine including;

2 corydoras
5 baby(dime-quarter size) peacocks
2 yellow labs
2 acei youngsters
3 adult peacocks(one born with 1 eye but it was a freebie and the other fish seem to not notice and hes a beautiful creamsickle color)
1 med-large green terror cichlid
and my texas green.

+ 3 crawdas, a freshwater eel, and a moss ball

i also believe my corydoras are a bronze female and a male leopard, i put them in a plastic frame netted breeder cage because of their frantic behavior but i have no idea how to tell if they are actually male and female, im pretty sure but nothing i have read has been specific enough to make me 100% sure.
