Sexing the Fish

Cichlids,
swordtails.
Requisites of courtship
make them dimorphic.

How much we
change ourselves for love:

I score my fingernail
down your side and see
edge of earth,

attainment of the improbable.
The cut that comes
from saying one wrong thing.

Their anal fins
shaped like triangles.
Huge humps on the head.
Tubercles
that look like little parasites.

In a koi pond
a female's ripe abdomen.
