Betta deformity

[Kieflow]

I have a crow tail female that I have for about 5 months and bought her as a juvenile. She has grown a lot since I bought her and recently within the past month she has started looking deformed with a crooked body and distorted face.  I currently have her in a quarantine tote because I am unsure as to whether this is a genetic deformity or some sort of disease. She is a picky eater but the food she does like she has a healthy appetite for. If anyone can point me in the right direction as to what I am looking at it would be appreciated!

We’ve lost 2x beautiful females that we special ordered. They looked great for awhile, but both developed similar problems (not exactly like yours, but some sort of abnormal internal growth under one gill). It may be just due to  intense inbreeding that shows up over time. I’d love to learn otherwise. Other bettas we’ve kept have done much better for us.
