My tetra loss

One of my tetras died yesterday. I found it floating in the fish tank.
Minutes before I was watching it swim about " excited"
because I had turned on their light and fed them.
Did it suffer with angst and pain?
Did the others lament in witness of its death?
Did it know prior to departure from this mundane
stage of the void that would replace life?

My query is; whether there's that emotional tug
of fear, of tears, of loss, loneliness of years
among other living entities,
as they appear in human beings?
Is our human empathy so forgotten
and the choice of ignorance so begotten,
to think that we humans are the only entities
with Love and suffering?

We manifest insensitivities toward our own humankind,
watching them in apathy as their children die.
We share not our food, our warmth or our clothes
we give not or our time, our love or our voice.
If so, why do we purport to care about other life forms
when they look in our eyes so deep,
their paw, their beak or their fin lay upon our hand so sweet,
they gently depart alone, 'quietly in the night'.

This interest at such grand philosophical scale
from the loss of a life form so small,
is comparative in cognizance,
of how we've not cared for our air;
How we've not cared for our seas;
How we've not cared for our land;
Where all other life forms exist.

One must remember, the words in a book of importance;
"...man will be judged by how they take care for the "least of us".
"Least of us" is concerning all forms of life that co-exist with us.

I'm sadden for my other tetras and their loss.
