yasha hase gobis

[traib]

Does anyone know--are yasha hase gobies sexually dimorphic? I have a pair, one of which has a long white dosal ray and the other has a long black and a long white dosal ray. Possible sexual dimorphism:notsure:

On closer inspection it may be that the gobi with only the white ray could have the beginnings of a black marking, but not sure. These guys are hidden most of the time and they reside at the back of the tank so it's difficult to see them well.

possibly but something that suttle doesn't usually reprsent ---...just dif color pattern......not an expert but i would just guess it to be a color morph (like in a clown goby)

Fishes seem to be, in general. the exception to the rule that diffeances in color represent sexual dimorphism especially in promenent parts of the body, for instance a peacock's tail. As the rays of the dosal fin with yasha hase gobis are promenent I thought that I found evidence of sexual dimorphism, and like a peacock's tail a female attractant.
