Not sure how to fingerprint Paradise FTP (searching for "Welcome to Paradise" also returned some non-relevant results) but there aren't many that contain "paradise" in their welcome banner.
Shodan also fingerprints lots of other FTP software (check out the "Top Products" section):
ProFTPD is by far the most popular choice at the moment.
Note: Doing a search that uses a filter (ex: "product") requires a free Shodan account. None of the above require paid access, you just need a free account.
