Livingston in "Devil's Due".
Livingston affected by Barclay's Protomorphosis Syndrome.
Livingston was an Australian lionfish kept by Captain Jean-Luc Picard in his ready room aboard the USS Enterprise-D for the duration of the ship's existence. The spherical aquarium was located in the corner of the ready room, next to the viewport. (TNG: "Encounter at Farpoint")
In 2364, Lieutenant Commander Data examined Livingston's fishtank very closely with a magnification glass, as the android was implementing some of Sherlock Holmes' characteristics at the time. (TNG: "Lonely Among Us")
When visiting Picard in his ready room, Berlinghoff Rasmussen examined the fish and knocked at its aquarium. (TNG: "A Matter of Time")
The Borg Hugh examined Livingston very closely when he was beamed into the ready room in late 2368. (TNG: "I, Borg")
Both Q and DaiMon Lurin took great interest in the fish in early 2369, closely examining Livingston in the tank. (TNG: "True-Q", "Rascals")
Later that year, Captain Edward Jellico requested that Livingston be removed from the ready room after he assumed command of the Enterprise. (TNG: "Chain of Command, Part I")
When visiting a holographic representation of the NX class Enterprise, Deanna Troi wondered how Captain Jonathan Archer could have survived without a fish tank in his ready room. (ENT: "These Are the Voyages...")
After being affected by Barclay's Protomorphosis Syndrome, William T. Riker attempted to break open Livingston's fish tank, possibly in order to consume him. Fortunately, he did not succeed. The fish had been affected by Barclay's Protomorphosis Syndrome as well and was transformed into a jellyfish-like creature. (TNG: "Genesis")
Q thought Picard was probably worried about his fish more than his ship and his crew after the captain saved Humanity from the effects of an anti-time anomaly in the Devron star system in 2370. (TNG: "All Good Things...")
Livingston was given a much larger aquarium by 2371. Unfortunately, the Enterprise-D was soon destroyed, although Livingston's tank remained intact and survived the crash of the saucer section on Veridian III. (Star Trek Generations)
For a time, Livingston was present in Picard's ready room on the USS Enterprise-E, in a much larger tubular aquarium. (Star Trek: First Contact)
- Livingston was named for producer-director David Livingston. The fish was never called by that name in an episode, but was named behind-the-scenes by Star Trek: The Next Generation production staff. Livingston's aquarium was not readily visible in Star Trek: First Contact, but production photos of the set reveal that it was present. Livingston was not part of the set for Star Trek: Insurrection and Star Trek Nemesis.
- Livingston was portrayed by a Red lionfish (Pterois volitans) in nearly every appearance. Only in "Devil's Due", the fish had changed species and appeared as a Radial firefish (Pterois radiata).
