I don't know but I look forward to reading what anyone who does know has to say!
Me too! 
Although I did find this:
GENDER: Males have more bars on their caudal find than do females.
Also, supposedly males have a larger and thicker anal fin.

Like all other memebers of the Polypterid family the males anal fin is aprox twice as wide
as the females and has a more pronounced muscular structure at the base-Anne
Reports of accidental captive breeding have been reported

I see, just like the bichirs. Well I saw on one website (forgot the link) about the rays of the ropes (dunno what are those) that male have 10-14 rays and female have less than 10 rays. Is this even true?

I haven't read it myself, it's one of the few journals I can't access for free and it's not well archived, a copy costs 150 Euros. I know someone who is trying to get a copy and also to look at current research being done in Germany.
My two look exactly the same so they're the same sex but I'd have to look at more ropes to compare the size of the fin.
I've also heard that the coloration is different, but I've never seen that written in a source that I would consider reputable.
