Oranda only using one gil

[bpowell487]

My oranda is only using one gil and the affected side seems to be swollen. I understand this swelling could be wen growth but it’s most prominent on his affected cheek and mouth. 

He also hides in the upper corner of the aquarium and will occasionally tip forward. 

I’ve dosed the water column with general cure.

Only new additions are some wood I put with Java Fern and Bucephalandra.

All other goldfish are fine.

Yes he’s eating. 

I’ll test ammonia and get a picture of him in a little bit (lights are currently off)

His mouth looks a bit better today and I’m noticing a bit more movement on his gil.

Just performed a 30% water change because I found my buddy breathing heavily at the bottom of the tank. 

Removed decor/plants I care about in case you suggest dosing with salt. All other fish are unbothered. 
 

Ammonia was 0.

It's difficult to tell off the picture it could be a bacterial infection with the symptoms your describing I would treat him with maracyn and aquarium salt 1 table spoon for 2 gallons
