Does helfrich fire goby change sex ?

Nemateleotris helfrichi
Anyone knows about this kind of goby does it change sex like other kind of fire goby ?

It does not. Helfrichi are actually a type of dartfish/firefish. I do not believe any of the dartfish change sex but could be wrong.

I rolled the dice on two juveniles and while they were best of buds growing up after they matured things changed. They cannot be in sight of each other or they fight (one is much more dominant).

Is there anyway to sex them ?

Cuz I have a pair they never fight so I'm wondering if we can sex them

Really hard to sex them. There is a post:

How long have you had them? Like I said, mine were inseperable as juveniles so the fact they do not fight now is not definative.
