Hi! I have a small tank with glow fish, albino Cory cat, tetra and 2 algae eaters. My glow fish was fine then over night this happened [photo attached ]and 2 hrs after I saw him, he passed . The following morning same thing happened to my tetra. Fortunately my corycat and algae eaters are still doing great. Does anyone know what disease this is? When he died he has a lot of white stuff in his mouth as well.
Any help is appreciated.
