So between last night and this morning I've been noticing his fins are slowly getting worse. Everything went a-okay yesterday, and I've just finished his first 50% water change today, but-- his poor fins just keep getting more and more ragged.
His behavior hasn't changed-- he's still very happy to see me whenever I go to look at him, still does a little dance for me, and he's still eating well.
Is there anything else I can do for him? Should I try Stress Coat? Or do I just have to wait for them to heal? I know it's only been a couple days but they just keep getting worse and I feel so bad for him.
Here are two pictures from last night of him floating in his quarantine cup, and two from this morning, right before his water change.
