[Killietalk] Sexing N. fuscotaeniatus

["Mark Pearlscott" <mark at pearlscott_com>]

Hello All,

For those of you that have N. fuscotaeniatus, you know that it is hard to
sex as a juvenile.  I'm wondering if anyone has any tips for making it
easier, such as:

On the males, the anal fin is more rounded and large edge is less vertical
when extended.  By contrast, the female's anal fin is more triangular in
shape and the large edge is more vertical when the fin is extended.

That is a difference I have noted, but of course it means that you need to
see an extended anal fin on the fish in question.  Any other observations
would be greatly appreciated!

TIA,

Mark
