Problem you are having:
1. A few days ago I noticed a small swelling/welt on the underside of my rays disk. No apparent redness but over the past 3 days the swelling has increased. It has not seemed to have effected his appetite or activity levels but I'm worried this may be something more serious. First day I noticed I did an 80% water change. Each day since I've done a 25% change
I first noticed the issue the day after I added the manzanita wood.
