I'm so sorry, Nuri. At least you took care of him (I hope! My sis let her betta bowl get gross to the point where you could smell it coming down the hallway, and wondered why the hell the thing died. I cleaned the bowl a few times just because I felt sorry for it.) and he was happy and he made you happy.
I can just picture those assholes across the street digging up Yugi and showing him to you.
Asshole: We have your fish.
Nuri: Why did you steal my dead fish?
Asshole: Because it's the closest we'd ever get to getting any.
