Sexing

[Demon_fish]

anyone know a good way way to sex a silver arowana at 2.5"? if there is no way at that size how big do they need to be to sex them

only way to really know is to have a pair and see which one lays eggs and which one holds them. my LFS says that you can tell by the lower jaw. if it sticks out more then the top its a male. i have 2 aro's and one sticks out and one doesnt i hope its a m/f pair

Try here to search for sexing arowanas. This topic has come up many times.

I thought that too but I highly doubt this concept.
