    Looks like 14 babies out of the 2nd hatch finished the yolk sac…. so the net did work.
    The 3rd spawn was a failure; not a single egg eyed up… I guess the male did not do his part. :(

    I don’t believe the bacteria part…something else is in play. the 14 from the 2nd spawn were in a sterile 5g and they did just as well as the previous in a dirty established tank. One interesting thing to try would be to see if one can use sand instead of a net… i have a feeling it may work just as well….

    If the eggs are not fertilized, has other causes, Mike. Then you need more water change, a lot and often. Phosphate / nitrate makes zhoui men infertile.

    What’s the maximum size of R. zhoui guys? Type description says 3.6 cm SL but am guessing they grow a little larger than that?

    Jutta will know better, all of mine are young, but I’d guess 2″ for males, 1.5″ for females.

    60 mm including tail, Matt

    So around 45 mm SL? Are females always smaller?

    Yes, the size is right so. And females are not smaller every time. Sometimes they are as large as males.

    Ferrika,

    If I may bother you again: what do you feed 15-20mm juveniles?
    (They are doing fine on artemia alone, but maybe it is time to supplement with something else).

    Anything that fits in their mouth. Mike :-) I’ll start with my pups always already to feed live and frozen food as soon as they are 1.5 cm tall. Mosquito larvae, tubifex, frozen brine shrimp, copepods, etc.

     

    They look very well, Mike. Good job!

    Well done and well deserved!

    In my opinion you are amongst the foremost experts on keeping and especially breeding Rhinogobius spp. On top of that you are capable of supplying superb photogrphy to go with it. No need to say more. :-)

    Regards

    R.
