Chatting with the Fish

In chatting with the fish I came to know something strange;
They segregate into two styles well worth studying:

The fighting fish, gourami, oscars, and the like
cling to self, attach to mates, and protect their nests.
Honor crazed and fierce, they are instinctual fighters,
snapping and biting their fish friends most insanely.

The other kind, like Tilapia, are curiously different:
they make no effort to dominate a mate as their own,
they wander like ascetics, hearts like monks,
leaving their eggs behind without a care.

They are just like homeless wanderers,
rather than those stuck on 'Ego' till they die.
