    After working with these fish for almost a year, I have a successful spawn.  I took possession of these fish on July 3 2012 from my good friend Stephan Tanner.  I have 2 females a 1 male fish.  This is the male pictured below.

    I had them set-up in a 20 gallon long with a generous portion of moss and while the seemed ready to spawn they just never pulled the trigger.  After moving them into a 40 gallon breeder with no moss, but some java grass floating they finally spawned.

    They are not aggressive egg or fry eaters as I have around a dozen 3 week old fry still in the tank with the adults.  I though this might be the case for when they were in the 20 long some young Danio aesculapii found their way in with the Devario xyrops and were not harmed.

    The 40 breeder is on a higher level than the 20 long some I’m assuming that the higher temperature had something to do with triggering the spawn.  I have not had much luck in photographing these fish, but will try to get some photos of the adults as well as the fry.

    Congratulations! Sure would love to see photos.

    FWIW, if Matt decides to add a profile for them, the description is freely available.

    OFT: Stephan had some nice danios before he moved (Himalayan lemon I remember plus something else)… did you end up inheriting them too?

    Thanks Mike.  I got the Danio meghalayensis before it was certain he was moving up north, and then I got the Devario xyrops, pathirana, aequipinnatus, devario and Danio feegradei when he knew we was moving.  The plan is that I send him fry when he’s set-up again.

    I pestered him so much about the Danio meghalayensis that he finally just gave in and sold them to me.  LOL  Stephan is a great guy and a fantastic friend.  I’m a better fish keeper through my association with him.

    Thanks for the confirmation Dennis, and please do keep us updated on the progress of your fry. I’ll try to add a profile for the species this week.

    Sorry it took so long to get back with photos.  I’ve been extremely busy and these fish are very hard for me to photograph.  The photos are not the best I’m afraid.  The fish are in a 40 gallon breeder and it’s not in a good spot to get quality photos.  I wish I had been able to photo document these guys like the D. meghalayensis…..  maybe next time.

    These guys are very reflective and most of my shots came out as over-exposed and you couldn’t see the bars on their sides.  At any rate, they are around 6 weeks old and nearing 1 inch in length.  They seem to be growing at a very quick rate, but perhaps that’s just me.  It looks as though I have about a dozen fry.  I would very much like to get another spawn from my adults as I have on the single male and 2 females.

    Cheers – Dennis

    Thanks a lot for coming back Dennis the young ones look really good. Did you raise them alongside the adults?

    Hi Matt, you are most welcome.  Thank you for providing us with such a fantastic place to hang-out and talk fish!

    I did raise them alongside the adults and that was one of the factors contributing to the difficulty in getting good photos.  Almost daily, I would look at them and think that I should remove them before the adults ate them, but they never did.  The tank has a generous portion of Najas guadalupensis, so the fry did have ample cover if and when it might have been needed.

    My adult fish are around 6″ in length and have a body shape very much like Danio dangila.  They do appear to be thicker and if put on the scales, I believe they would weight a good bit more than the similarly sized D. dangila.  My adult fish have also lost the barred pattern on their sides like most of the photos you see on the Internet of Devario xyrops.  If memory serves me,  Stephan said these fish came in a by-catch to Aqua-Global and he obtained them from his friend Ingo Seidel.  As such it’s impossible to know the age of my adults.

    To say I am happy that the adults produced a successful spawn would be a great understatement.  To the best of my knowledge, these may be the only xyrops in the US.  The additional 12 fish gives me a bit more breathing room, but it is very unfortunate that I have only the one adult male.

    Cheers Dennis, but it’s the people that make it. :)

    Think I need to make an adjustment to the maximum size information in the species profile – is that 6″ standard or total length?

    I was a little overzealous in my measurement!!!  😳

    They are more like 5″ total length, the same length as my Danio dangila.

    Well almost 18 months after spawning these fish, I have finally taken a decent photograph of them.  LOL

    F1 Devario xyrops

    I’m hoping to see if the captive bred ones are easier to spawn than the wild caught fish.  At any rate, I now have enough fish to form some opinions about them.

    Nice looking fish Dennis.

    Its too bad we don’t see more of these uncommon fish in the states.
