    I have a group of these I'm working on as well. Still in the pairing process. Good Luck :biggthumpup:

    If you're referring to the visual route, that's not reliable one from what I've read. I do welcome any information you may have to share, though. Information is good :) Call me when you're around. I have plenty of rotifers (and ciliates).

    sexing the fish is very reliable. in this pic, the larger is the male.

    male is bottom fish.

    the pelvic fin on the male has a black tip, females don't show this.

    Thanks, interesting... got a reference for these facts? Where did you get that information?

    Here's the information I was referring to:

    "There are no readily apparent external differences hobbyists can use to differentiate between sexes. In some instances, pairs have been collected from the wild where the male is the larger member, while in other instances it is the female that is the largest. There have been reports (Baensch, 1994) of using the dorsal spine as a means to indicate the sex of the animal, but after reviewing the research data for this species, that would seem a highly unreliable characteristic. For all intents and purposes, there is no way a hobbyist can tell the difference between male and female Stonogobiops while the animal is still alive."

    Reference: http://reefkeeping.com/issues/2004-01/hcs3/

    It is rather old...

    might be talking about other Stonogobiops, but the yasha is easy.

    go ahead and pair them like I described. instant pairs

    my first order of yasha gobies was all female. I couldn't find the black patch that I heard about on MOFIB. I ended up taking home two females in hopes of a pair, and one killed the other... the 2nd batch that came in, 5 female and 1 male. the male just looked like a male, he had two dorsal spikes. then I saw that black patch and confirmed him a male.

    I ordered a pistol shrimp for them to have, but shrimp arrived barely twitching and soon dead. I'll order more next time. wouldn't mind having a pair of pistol shrimp with my pair of yasha

    Okay so you're mostly basing this on behavior. I did find this reference:

    "Sexual dimorphism.—Besides the shape of urogenital
    papilla (pointed in male, rounded or swollen in female),
    a single male paratype (URM-P 8332) had dark colora-
    tion on the posterior part of the pelvic fin, whereas other
    female type specimens did not have such coloration.
    Among files in KPM-NR, four pairs of the species were
    photographed (KPM-NR 7109, 9459, 11183, and 11245),
    all of which comprised one with and the other without
    dark coloration on pelvic fin. Accordingly, it is highly
    probable that only the male has dark coloration on the
    posterior part of the pelvic fin."

    Reference:
    Stonogobiops yasha , a new shrimp-associated goby from Japan Tetsuo Yoshino and Kazuhiko Shimada

    Thanks for pointing me in, what could be, the right direction.

    I assume you're talking to me based on your recent private inquiry.

    Until we have solid proof of Yasha gobies spawning in captivity I think we should keep an open mind as to what a male an female look like. As the data I presented below points out, it is likely that males have a spot on their pectoral fins. However, I personally do not accept this as fact at this point.

    I know people have collected spawns of this species before...will Mr. Vossen be the first to rear it?

    New to TCMAS, but I joined because of this thread.

    I picked up a pair of Yasha's locally and have not noticed much sexual dimorphism. There is no black tip on the pelvic fin. There does seem to be a difference between the dorsal fins; one is thicker than the other.

    welcome!

    I really would believe that you have two females, but time will tell. they may be getting along due to being new to the environment, could change as they get settled in.

    let us know how it goes :)
