As a kid I used to have a pair of fishes. The first ones were secretly replaced when they died but I was aware for the heirs. Although for some reason I always named them the same : one was Juliette and the other ... Gédéon.
No one knows where I found that name it's still a mystery 🤷

(Bonus: I always have lived with pets, tho we were quite unlucky with dogs. But apart from our first cat who got run over by a truck not long after she had her babies the cats have been fine)
