Helloe everyone. I haven't been around much due to life, but I have had my red breast sunfish, Morsel, for a while, thanks to the members of this organization and forum.
This week he developed a bump on his head. It appears to have grown over the last few days. If anyone has any idea what it could be and what I should do about it I would appreciate it.
I do water changes of 50% or greater about weekly. I introduced some fathead minnows for him to him to enjoy 5/16. Not sure if they could have given him something, but they never have before. I haven't pulled out the test kit yet for the water because of the regularity of changes.
I wasn't able to attach pics but I have linked to them below.
