My Betta has been doing fine (He's the one that had the popeye back in December around Christmas).
He's perfectly happy in his 10 gallon filtered tank. He has a bunch of silk plants to hide in and a coffee mug that was well rinsed before being put in.
However, when I went to do his water change I noticed that he lost the color in his fins and has a not-awful case of fin rot (I caught it early, THANK GOD). His fins are normally a very pretty red color, and now they're brown, and it's a sickly brown.
This is a recent development, because I SWEAR he was not like this two days ago.
I treated him with some Maracyn Two because I have some left and it says it can be a treatment for fin rot.
I feel like he's bloated, but at the same time I don't think he is, I think it's just that he's still a bit skinny from his "I don't feel well so I'm not going to eat" phase.
I feel really bad that he keeps getting sick :(
There's the pictures.
I'm so worried about him :( Advice?
