For the past day or so, he just hasn't been his usual nippy, jumpy self. He is hiding from me, fins are frayed again (haven't quite healed up since he chewed them back when) and looks pale. He is not bloated which is different from my last 4 who passed.
I am treating with Maracyn Two and stress coat. He still comes ups to see me, but usually he sees me coming across the room and is already jumping up before I get there.

I cannot loose anymore
betta, but especially NOT Sebastian.

He is in a divided tank with JB who is fine. The toughest betta I have had in a long time. He had fin rot when I got him home from the
LFS and recover completely from it. But I am treating the whole tank just incase.

Everyone cross the fingers for him...I do have hopes.
