Well, Oranos has a pretty bad case of fin rot, having lost almost half of his caudal fin since I first noticed it a few days ago, his other fins don't seem to show too much rotting. I have added salt and been using Melafix for the past two days. I was just wondering if there was anything else I can do for him. I can't get other medications(other than Pimafix) without ordering online, so they won't get here for quite a while.
The important info:
Tank - 5G
Cycled - No
Filtered - Yes
Temperature - upper 70s all day
Parameters, I don't remember the exact numbers, I checked after the last water change(Monday) and it was all normal.
I feed him 2-3 Hikari Betta Biogold pellets twice a day.
I change the water at minimum a 100% change each week, sometimes with smaller(25%) changes in between. I vacuum the gravel each time.
He has no unusual symptoms or behavior besides the fin rot.
