Well, when I first got Maccies from Petsmart (one where they do a decent job of tending to their bettas), he seemed alert and happy. After a few days, I began to really really worry something was wrong with him. As the week went on, I grew more and more worried about him, to the point where I was considering bringing him back. Then, he got better.
When I moved back into my dorm (a good while after he's been acting/feeling strange) I sent up my divided 5 gal with the boys. They both seemed to enjoy the space, especially Alle!
...But Maccies grew unwell again. He was constrantly hunting for Alle (Alle not so much), stressing himself out, not eating because he could see Alle, etc. Even when he couldnt see Alle (through a doubled up divider), he was still freaking himself out :(
I noticed his scales were a bit raised and took him out of the tank and into a 1.5gal QT to see if he'd improve. He did. Like CRAZY. He was his old derpy self again :D
...But when I put him back with Alle...
Right back to being stressed and unwell :c
I decided it wasnt fair to Maccies to have him in a place he couldnt fully enjoy his life in. My friend down the hall absolutley fell in love with him, so I decided to let her care for him (shes exstatic!) She's had bettas before and has me as well, so I know hes in good hands.
It might be just Maccies, he's always been a little on the frail side :'c It wouldnt be right of me to keep him in a life of constant stress and unsettledness just because I wanted to keep to boys :'c <3 Maybe another time Ill look for another boy, who knows? But not now.
