I posted here about a week ago worried about my betta’s potential fin rot. Shortly after, I added almond leaves to the water to promote regrowth. In that time I feel that he’s gotten worse, and this redness is spreading throughout his body. I’m about to send him to a hospital tank with SeaChem Paraguard. I’m very worried about him, as this is the first time I’ve had fish in years. I’m attaching photos, the first two are from last week, and the last one was from last night.
I sincerely apologize if I’m spamming the subreddit, I’m very worried about my boy. I had a really helpful commenter last time who gave me a ton of info, but he still seems to be declining.

I made a post asking for help without paying the obligatory betta photo tax. This is Dog, he’s… some kind of betta, I’m not exactly certain, and he’s the best. He ate from my finger for the first time today. He loves to see people go by the tank and has even learned how to beg for food.
Just wanted to show him off!

This is my young man named Dog. He’s the first betta I’ve had in years, and I really enjoy his company.
I just noticed some weird coloring on his fins, it’s starting to scare me. I don’t know if it’s natural color or if he may be hurt.
The first photo is from two weeks ago, and the last two were from yesterday and today. I don’t know if it’s fin rot or unique color expression, and I’m very worried about him.
Any help would be appreciated, and I’m sorry if this post is out of place, this is my first time using reddit.
