[emperorsnakehead]

do you know about the emperor snakehead fish (toman bunga) and bichir @ palmas fish (ikan naga)?

i still don't know how to differentiate between male and female..
some said we can see from above (for snakehead), if the head is round and big, it is female..but if the fish is still a baby (like mine), it is quite hard to differentiate..
and for the bichir, some said we can see from it's fin..if the fin is longer, it is a male one..

but i still cannot 'believe' to some facts if i don't see any pictures about how to differentiate their sex..(1 picture equal to thousand words)..
and i still cannot differentiate them because from my eyes, i see all of them are the same..
