I would like some help :) Thank you in advance!

There are many different causes of popeye. The Epsom salt that you used may have helped reduce the swelling, but wouldn't necessarily treat the underlying cause. The metronidazole would have helped if the issue was due to anaerobic bacteria or some parasites. But there are other causes of popeye, too.....

Can you post some photos? If you can get some pictures of his eyes, his fin coloration and deterioration, and an overall side view of him, that would be very helpful.

Are both eyes equally swollen, or is one more swollen than the other?

Also, can you fill out the form below so that we have more information? Answer what you can, and leave anything else blank.

Initially both were swollen and red, and now one of his eyes does look less swollen than the other one and not red. The other remains really swollen and red.

How has your betta fish's behavior changed? No I got him already sick so I am not sure; he does seem a bit lethargic at times, but manages to scavenge for food
When did you start noticing the symptoms? A while back ago. I am not sure...2 months or more? He started to loose a lot of color
Have you started treating your fish? If so, how? Epsom Salt as directed by a member here and I have added Metronidazole to his food intake. Seems to be helping a bit
Does your fish have any history of being ill? Yes I got him with Popeye. I did not know, but did give him a good home (his current home); then he started loosing a lot of color. Someone here was kind enough to diagnosed my Betta with Popeye. The member instructed me to add Epsom Salt and do a treatment of Para guard with Tetra. Both I have done and they have helped, but he is still very sick
How old is your fish - OR - How long have you owned it?For a few months, but the Betta is fairly young

You can see how it has progressed; although he looks better he still does not feel that great. Changed substrate and filter as requested by the person who helped me the first time.

Thank you for your help! I hope that I can get better pictures tomorrow. I do not have the tank lights on it is just room lights. I read that lights can be bothersome to fish with Popeye so I don't have the lights on at all. Since I am using the Epsom Salt I do not have any plants in the tank. Again Thank you for helping me. I hope this little dude can get better.
