I'll try to get some pics of him tomorrow
I was thinking fin shredding was fin rot, so I'm glad you brought that up, Tony.
In my "nutritional arsenal", I also have spiriluna,
brine shrimp, and bloodworms. I plan on giving him some bloodworms tomorrow dipped in garlic juice, but I wasn't sure if the spiriluna would help, too.
I'm no trying to turn him into a "cause", but it's important to me that he pull through and get back to his wonderful self. If I can do it without meds, I can show how important a cycled filtered, heated tank is for a betta and maybe make sure when he does heal, he has a better home to return to.
Also, I don't know if this will help determine what is going on with him, but he has a tumor. It's gotten smaller than it used to be. I don't know if she used meds for that or how it shrunk, but if that information helps, I wanted to make everyone aware of it.
