yea, fishes have life too...
once i heard that my way was wrong...i returned the fishes and start all over again..
in fact i changed focus from rearing nice looking fishes....to providing them a happy enviroment.
Thought i do not believe in feng shui , but i believe a death in the family will cause bad luck.
so if ur 40 fishes die, u kana bad luck 40 times...
think about it.. !!
