Obviously the history of Greek word ichthys is much older than early Christian adoption of the word. I don't know many but ichthys is related to some ancient sea goddess, before the birth of Christianity traditionally the word had represented the womb, great mother, dolphin, etc. Then early Christians found the spelling of acronym happens to be the same as their faith then they started using the sign of ichthys to represent Christians.
This is not a fish story.
