I have one Senegal Bichir that I bought about 14 months ago and was 3" (7.62 cm) when I got it and it is almost 9 inches (22.8 cm) right now. I know that you can usually sex them at this age and that the males have a larger anal fin but I do not have one to compare mine against. I don't have a picture atm but if anyone would be able to sex it by picture I would be more than happy to get one.
