It is very late and I just now noticed two of my 9 neon tetras have white growths on their mouths. They have good color and do not show any behavioral changes. I am going to do a 50% water change then go to bed.
Tomorrow I hope someone can recommend a treatment. It is a 10 gallon well established planted tank. The fish have now become full grown. I am sick about this. I do not have the means to set up an isolation tank so if there is a treatment I will need to treat the entire tank. I have been working a lot and have not been closely observing the fish like I did when the tank was first set up. It looks like I missed something that should have been noticed sooner.
