The Blue Fish is a fish that appears in Pocket God Facebook.
The Blue Fish makes a brief appearance in Pocket God Facebook even though the Orange Fish replaced it. When the player drags a Bomb Fruit into the water, there is an explosion. Originally two Blue Fish, a Green Fish, and an Orange Fish would float up dead, but one of the Blue Fish was later changed to an Angler Fish. They then sink back down without really doing anything except humour the user.
This is also one of the fish that a pygmy can now catch.
