Season 1 (Spring 2023) The inaugural season premiered April 18, 2023, and ran for six weeks through May 30, 2023. It featured eight contestants from various locations across
North America living under the original Fishtank format. The season concluded with Josie Martinez as the single winner, who received a cash prize of $35,000. During the program, additional characters (called "Freeloaders") were introduced into the house. They could not participate in the competition for the final prize money, but were able to interact with the fish, and, should they succeed in tormenting one enough to make them leave the house, they would receive $1,000. Most of the freeloaders were either fans of the show who wished to join on their own right, or well-known figures from niche online communities; however, some were former contestants who returned with a new role after leaving the house.
Contestants Season 2 (Winter 2023–24) The second season aired December 18, 2023 through January 28, 2024. This season expanded to ten contestants and relocated to a new house with a
1970s retro theme and the fish dressing in period clothing. Unlike the first season, most of the contestants entered with at least some prior awareness of the show’s general premise, though at the outset, production told each contestant individually that he or she was a "
plant" and the sole participant who already knew about
Fishtank, and that all of the other contestants were unfamiliar with both the program and Sam Hyde; this conceit quickly collapsed as the cast realized that several of them were in fact aware of the show. The season was subsequently presented as an increasingly grueling and psychologically demanding competition, with production gradually pushing the house toward the so-called 'hell house' phase as conditions deteriorated and the property was progressively damaged over the course of the run. A further storyline involved the fictional "Initiative Group", a made-up cult devised by production and introduced through the attic segments; the conceit was originally meant to continue through the full 42-day season, with any eventual winner needing to join the group at some stage, but the storyline was largely abandoned after about two weeks. TJ was the only contestant to be formally incorporated into the Initiative Group narrative before it was phased out, making it a distinctive part of his arc during the season. The finale took place in late January 2024, with contestant TJ winning the $50,000 cash prize.
Contestants Season 2.5 / Bloodgames (Summer 2024) Between the second and third main seasons, Fishtank aired
Fishtank All-Stars Vampire Bloodgames, an interstitial spin-off commonly referred to by fans and promotional material as Season 2.5. The event premiered on June 25, 2024 and ran for approximately two weeks. Unlike the house-based format of the principal seasons, Bloodgames was presented as an outdoor
live-action role-playing and
survival variant featuring returning personalities from earlier seasons. Unlike the main seasons, there was no single grand prize winner; instead, players aimed to "survive" the game's narrative and challenges.
Contestants Season 3 (Fall 2024, "Famous House") The third season began in October 2024 and ran into December 2024. It introduced several changes: the house location was upgraded to a large upscale residence, and the cast grew to a dozen contestants (the largest group yet). The season began under the false premise that the participants had been cast as 'Famous Stars' in a separate project titled
Famous House, presented to the audience as an over-the-top parody of
scripted reality television shows such as
Big Brother, but played straight to the contestants, who were selected due to their unfamiliarity with the original show. Subsequently,
Famous House gradually transformed to
Fishtank, progressively increasing the elements of absurdity and depravity ("
boiling the frog") until the "rug pull" moment on day 14. On November 24, 2024, after the true nature of the reality show was revealed to the "Fish," 12 new contestants were introduced, believing they were participating in Famous House. This created a situation similar to the one initially experienced by the original cast, except that this time, the remaining original Fish (Burt, Binx, Payton, and Simbal) knew the truth and acted as "Plants," playing along with the new cast. Late in the season, production left the principal house and shifted the remaining action to a
recreational vehicle. The mobile finale took the cast out of the house format and turned the closing stretch into a road-trip-style continuation of the show, culminating in a trip to
Las Vegas, where the season ended. Although Albert "Burt" Appouh was declared the winner of the season, production did not award him the advertised $50,000 grand prize as the prize money had been lost in a roulette bet during the Las Vegas finale.
Contestants Season 4 (Summer 2025) The fourth season launched June 13, 2025, intending another 42-day run. However, it was cut short on June 30, 2025 after just 18 days of live streaming. According to statements by the producers, all three potential filming locations raised zoning and safety objections, forcing the production to halt. No winner was declared; instead, the remaining six contestants were awarded equal shares of the planned grand prize at $8,000 each. This was the first season not followed by any
edited episodes release. Season 4 also marked the final hosting appearance by Sam Hyde on Fishtank. Public reaction to the cancellation was mixed, with viewers expressing frustration and confusion over the sudden end.
Contestants Season 5 (2026) The fifth season premiered on March 15, 2026 and ran through April 14, 2026. It relocated production to the Atlanta, Georgia, area, introduced a cast of ten contestants, and reduced the season length from roughly six weeks to 30 days. The season was hosted primarily by professional skateboarder and entertainer
Bam Margera, marking the first main season not fronted primarily by Sam Hyde, and a guest-host rotation was introduced including Margera, Neptune, and former contestant Letty. Season 5 also introduced several structural changes to the format. In place of the relatively spare house mechanics of earlier seasons, production added a more elaborate internal game system, including an in-house economy in which contestants performed daily jobs for cash that could be spent in a market room, along with amenity rooms that unlocked over time. On Day 25, season 3 fish Burt arrived as a freeloader and introduced the fish to "goo production" responsibility which required the remaining contestants to manufacture
slime within a newly designated "goo room" in preparation for the finale. The final competitors, James Drake and the Twins, faced off in a gauntlet of 39 challenges over the course of 24 hours which came down to a goo-wrestling tiebreaker won by James Drake who was awarded the $50,000 grand prize. As runners up, the Twins were awarded $20,000.
