Nero was a doubletail who I bought last week. He wasn't well when I bought him, but he wasn't apparently too bad, despite the horrible environment that cheap store kept him in, so I thought I could save him.
He wouldn't eat at first, though he did bite his tail. Yesterday, I finally got him to eat some, so I thought he was doing better.
This morning, despite all the effort I spent (and all the money, but I'm not as worried about that), he passed away.
RIP little buddy. I know I barely knew you but at least you died in a big, clean, warm, planted tank and not in a tiny container filled with your own feces.
