Worried: My betta's fins are damaged by a fake plant. Is it fin rot?

Pet's info: Fish | Betta | Male | unneutered

I'm Gabby, this is my betta blue, I got him about 2 weeks ago from Petco and I'm very worried about him. In his tank, I had a fake plant that supposedly was silk but I guess it wasn't and it really harmed his fins, I took it out but now his fins look a little weird and I'm really scared that is some kind of fin rot or something, but first I want a vets opinion and also see what you guys recommend doing, he's my first pet and my baby and I don't want him suffering, I would REALLY appreciate it.

Thanks for reaching out about Blue and including photos. Fins can re-generate but water quality must be kept pristine. Test and correct for pH, ammonia, nitrite and nitrates. Water additives such as anti-bacterials or others can cause more harm than good. If the fins become worse, a veterinary visit is needed. Good luck.
