Mr Fish died...

Poor fishy died out of a sudden. Sob. I just changed the tank water, cleaned the tank and put in more oxygen bubbles for him and he died....

I suspect he broke his spine. Because he can't swim straight, slanted to a side. Or it's the blood worms he ate everyday. Maybe it's not suitable for him. Or it's the air con that is too cold. Sigh. Anyway he's died. I don't want any pets anymore.
