Aquariums in movies and tv shows

I've been rewatching an old favorite, Homicide: Life On The Streets, since it came to streaming.
One episode, the murder victim had a fish in a bag in his possession when he was killed. The evidence guy doesn't want to take it into evidence. He tells Detective Munch to flush it. Munch doesn't have the heart so he gives it to his on again, off again ex who has a 50 gallon aquarium.

Spoiler

It turns out to be a Jack Dempsey and kills all her other fish. He says $4000 worth.
I have questions. What did she put in a 50 that adds up to that much? Why would she just throw a random fish in without knowing what it is? Jack Dempseys aren't an uncommon fish. How could a fish keeper not recognize one?

Awwwh Maan I loved Homicice. It was weird seeing some of its scenes been reused in The Wire by the same writers/producers.

In the film About A Boy right at the very very start the character played by Hugh Grant is a selfish loner living in a Batchelor pad to die for. Which includes a huge aquarium and is first seen feeding its solitary Betta.
I knew immediately what the closing scene would involve…..yes you’ve guessed it already: Hugh Grant feeding a lovely community tank surrounded by all his newfound multicultural shiny happy people friends.

It never mentioned what happened to the Betta? Maybe he’d learnt the true value of companionship as well?
