About fish

Something made me think of fish
not those in tanks which life must be boring
swimming around and around
until tired and resting at the bottom
wondering how to get out of this watery trap

Do fishes think or is it all instinct?
Say, two codfish meeting each other on the coast
of Greenland: hi, their old mate hasn’t
seen you around for a while? No, I met an escaped
farm salmon, but it didn't work out

It got broody wanted to swim upstream
being a bachelor, I took my farewell and escaped.
Chased and being chased that’s life
a proper fish instead takes its chances rather than
living in a glass tank
