Does anyone have any pics of the differences in anal fin size/thickness? I've heard that males have thicker anal fins, but I just need to know how much thicker.
 
I know there are pictures on here, if you do a search for sexing bichirs their should be several posts. Hope that helps.
 
The males anal fin is approx twice as wide as the female and more muscular-Anne
 
yeah the males is alot bigger also the males will sometimes streach out there fin and curl it to make a cup shape i don't think females do this the males do this to catch the eegs of the female dureing breeding

Yeah seeing this is actually pretty cool too.

fishlvr - A male's anal fin is MUCH thicker than a female. I find that the female's anal fin is almost see-through for 1/2 of it, while a males is almost fully colored in.
