Thanks. I will keep all this in mind... it always had a dull colour mouth? Not as orange as the female?But im thinking if coc was lurking on the body you may have had an infected fish
Not param problem my man it coilve been n spike but the fish doesnt look burnt so i woupd say more likely dormant parasites(no fault of your own can be dormant on any fish even one that looks healthy at the pet store(ask if they can feed and see which ones attack food thats the fish you want not mid drifter or some guy off the bottom the pet store is out to get your money and that being said look at how densly populated theyre sale tanks are it no wonder sometime we bring home something nasty... now this is a pick of amonia burn you can see how it affect around the gill plate of this butterflyfish(coperish blue hue)
Now this is a ocellaris with ich a bad fluke out brake notice the paleness and deteration of the slime coat as this poor fish gets eaten inside out
Third pic is marine velvet another sub species of ciliate notice complete
Paleness an blotches
Fourth pic is brooklynella notice the slime coat peel at the top of dorsal fon leaving streamers
