Rocky is a pre-named fish available in the Virtual Tank. It can be purchased from the rare fish slot in The Fish Emporium on very specific days by chance.
Rocky is a small guppy with a blue body and white fins and is unable to grow in size. Despite its small frame, Rocky finds ultravores palatable and even roars every time it eats.
Bugs[]
Rocky is known to be associated with a number of bugs regarding its disappearance from a player's tank.
In one possible scenario, using Walter's ability on Rocky causes it to disappear from the player's tank. Otherwise, Rocky may disappear on its own regardless of care, emitting an explosive noise and indicating possible death. Rocky has been known to occasionally return while other cases claim Rocky is lost forever.
Because of its tendency to suddenly disappear, Rocky has garnered attention in online communities where players speculate why Rocky disappears, what Rocky might be doing, and how to retrieve Rocky.
However there is a way to prevent this from happening, use the "hide" button to rocky whenever you're leaving virtual tank or leaving the game, the 'hide' button will make it impossible for rocky to disappear
Trivia[]
Rocky is possibly named after the movie character Rocky Balboa. Supporting this is his origin city (Philadelphia, Pennsylvania, the same city Rocky is from) and his "low-carb diet."
Funny enough Rocky Balboa is portrayed by Sylvester Stallone, and Sylvester being one of the alien in the game.
