"Herbie" is the nickname of a goldfish seen in the immortal's portrait, named by Dustin Browder.

The following section contains information from a previous version of StarCraft II which is no longer valid.

During StarCraft II development, on the highest graphic settings, the interface added more lighting and reflection to the glass of the immortal's tank. Herbie and other elements, except for the protoss' head, became less visible.

In the final product, the immortal's portrait changed a bit, but Herbie is still occasionally visible in-game, and can be seen if you open the immortal portrait in the map editor's visualizer.

Heroes of the Storm

In Heroes of the Storm, a similar goldfish can be seen swimming in the pod of Fenix. Fenix has a poke quote referencing the fish, and a "Fenix Gold Fish" portrait was added to the game.
