I wrote about the fish tank some time ago. Well , the fish are my sister’s. Still, since I’m the one who wakes up early, I feed the fish if I’m at home. ( I go stay at my friend’s place sometimes. )
Recently, one of the fish started swimming upside down. It’s still like this now.
See the pic:

Fish upside down

ah.. poor little fish.
I have no idea why it is like this now. Maybe it got injured? Still, one thing I’m sure of is that the fish is still alive. It can swim to the top or anywhere it wants and it can still eat.

The fish was still upside down. It just stayed at the bottom of the tank without moving much during the last few days, seemed to have stopped eating and died today. :cry:
