My angelfish was healthy, eager to eat and always swimming around, and 4 months later, it started to hide, when it breaths, it opens it mouth bigger than usual...(bigger gulps), and it also has red marks near its mouth, like it has a bleeding nose, fins sometimes clamped, it eats and spits, stringy white poo, what should I do? I read the internet that it could have a internal bacterial infection, I also have other angelfishes in there (all healthy), whatever disease this one has, would the others have it too in the future? How can I treat the angelfish if it is an internal bacterial infection, I read that you'd have to stick a needle in it with antibiotics, otherwise, its a goner since internal infections are harder to treat...
