In its original broadcast, "A Fish Called Selma" finished tied for 66th place in the ratings for the week of March 18–March 24, 1996, with a
Nielsen rating of 7.8. It was the sixth-highest-rated show on the
Fox network that week. In 2021,
Entertainment Weekly placed the episode fifth on their list of the top 25
The Simpsons episodes.
Empire, in 2004, called the episode the "high point" of the show's "long-standing love affair with
The Planet of the Apes", and cited it as McClure's "finest hour". In 2006,
IGN named the episode the best of the seventh season, stating that it seemed the "obvious pick". They called the musical the best moment of the episode and "maybe even the whole show". In a 2008 review, IGN's Robert Canning praised Phil Hartman's performance as "simply the best of any guest appearance on
The Simpsons". He concluded by saying: "Sure, [the episode's] writing is smart and the jokes are funny, but without Phil Hartman as Troy McClure, 'A Fish Called Selma' would only be good. With Hartman, it's fantastic!" Also in 2006, Kimberly Potts of
AOL Television named the episode the 14th best episode of the series. Dave Foster of
DVD Times praised the episode in his 2006 review, as well as Jeff Goldblum's participation on the
audio commentary. He stated: "for those yet to witness Troy McClure's musical take on
Planet of the Apes, well, you might say you haven't lived! Musical parody at its very best, the visuals and aural delights in this one brief sequence guarantee this season a recommendation being one of the most inspired moments of
The Simpsons many seasons." In 2012, Johnny Dee of
The Guardian listed it as one of his five favorite episodes in the history of
The Simpsons, writing: "Key to The Simpsons longevity is the minor characters who only crop up every season or so. And none more so than Troy McClure."
Gary Russell and
Gareth Roberts, the authors of the book ''I Can't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide'', were pleased that "Troy McClure gets a starring role at last". ==References==
