New fishy move in

my brother griffin has about 23 fish and 10 of them are big and so the big ones and the little ones live in separate tanks.  And at this time I am having renovations and the big fish have to live at the house that is being renovated and the little fish had to change houses.  This is about the story of them moving from  there standpoint.  One afternoon one of 5 fish that where the same type we should name him (george) found the crack in the tank. He told his friend and soon the whole tank knew.  they also knew it would take about 7 hours before griffin would get to home to fix this.  They where all going crazy they thought we are all going to die 1/5 of the water has gone down…
