Glow green

Glowing green encased in a body blue
Electrifying the surrounding blackness
By its vividness and natural colours.

Flowing in the slow-flowing streams
Surviving brackishness in waters different.

Being a pet in the Japanese homes or
Swimming in tranquil aquariums
Watched by the screaming kids/bemused adults,
Medaka is something for everybody:
A fish or a being strange.

A subject for scientific study for vertebrate development
A species taken in the outer space mission in 1992
And
A regular muse for the visual artists of the world
Across time and space!
A delightful tiny creature telling humans great lessons
About the value of the adaptability and hypnotic
Power of translucence.
