Pity my father's fishes

When home from Klang, my father's all big fishes died.

Today 6 of my father's baby fishes die.
Now left 4 baby fishes only.
They die also got pattern.
Some rotate like a roller coaster, some reverse (head down, tail up).
I think my father is very very very sad, because he is so love his fishes.
Haiz....... short life of fishes.
