Dying fish

How can a fish lived?
if you are not feeding it.
Yes!, there is an alternative
but until when it will last?,
until the seeweed dries up
or until the water lost its part?

The fish can be healthy
for quite sometimes,
but in process it will die.

will you let it die
if you already see it coming
or be blind, you leave it behind?.

Then, why not from the very first
let other be its life?
Is it because your heart desire
or you enjoy the favor you could have?
