I am happy because my guppies are playing their usual games:

The kissing game - they nuzzle each other and then dance in near liplock -

Hide and seek - round and round the stone caves they go

Bubble run - up and down the bubble wash

Circling - maneuvering to get an advantage. This is the coolest one,
their bodies bend at an angle and they flutter and display their tails and fins
in a dramatic, quivering fashion

Their names are Clatu, Veratu, Nictu, and Nemo - what a bunch of cards!!!
