-sigh- I keep having troubles with my Betta. I noticed that his fins were ripping apart, so I treated him with AQ salt. Then I moved him in a smaller tank to quarantine him, I do my best to do daily water change while I'm quarantining him. Now, I noticed that his fins are not even getting any better, and his colours are fading and now, it seems like under his gills, it puffed up a bit. What do I do ;-; help pleaseeeee. I want to save him.
