I wonder if he's being bullied by some of the other fish in the tank, and/or he's scraping himself on your decor. Large and frequent water changes can help him heal.
You have stocking issues if you'd like to discuss them. What are the dimensions of your tank?
I suspect she is scraping herself but I have not moved anything recently. I don’t think she is getting bullied as she is the largest fish in the tank. I think I might drill a larger hole into her favourite cave. About the stocking it’s 40h x 30w x 120l why what do mean about the stocking
A big size doesn't necessarily mean she's not getting bullied - little fish can bully big ones too.
Yoyo loaches should be in groups, but they're also nippy and can stress other fish, and I wouldn't add a group with your current stocking. I'd rehome it.
I think you have too many cichlids in your tank. I might rehome at least one species.
The scissortail rasbora should be in larger groups, but they need cooler water than the angel, and really a bigger tank too. They may look small now, but they get large as adults (6" long, which is big for a schooling fish). I'd rehome them as well.
