I noticed about a week ago that my Betta was missing a few scales. Since then it has gotten progressively worse each day! He is now missing almost 50% of his scales.
I check the water quality twice a day almost every day. All parameters have been where they should be. A few days ago I did a large water change to make sure it wasn't something in the water.
I also started treating the water with Tetra LifeGuard All-in-One because I read some threads that stated scales loss is due to bacteria and others stated it was fungal. I figured an all-in-one was my best bet.
The only thing my Betta shares a tank with is an Apple Snail.
Any help would be appreciated. I am attaching pictures. The first was from 2 days ago. The 2nd is from today.
One of my biggest concerns is making sure he isn't suffering.
