I know I am late to the party, but have the same question: I have a very similar shot, same species of fish (which i agree with your input), but I have narrowed it down to Thysanostoma thysanuran or Thysanostoma loriferum. This is the only site, with a scientific background that has any details of this jellyfish. It is in Chinese, but a translator works good. http://fishdb.sinica.edu.tw/chi/importpic.php?id=T04
