mikevParticipantLooks 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….

FerrikaParticipantIf 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.

MattKeymasterWhat’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?

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

FerrikaParticipant60 mm including tail, Matt
November 21, 2012 at 8:23 pm #349368
MattKeymasterSo around 45 mm SL? Are females always smaller?
November 21, 2012 at 9:53 pm #349370
FerrikaParticipantYes, the size is right so. And females are not smaller every time. Sometimes they are as large as males.

MattKeymasterOk great, thanks both.:smile:

mikevParticipantFerrika,
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).December 4, 2012 at 8:07 pm #349433
FerrikaParticipantAnything 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!

RüdigerParticipantWell 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.

FerrikaParticipantOh, thank you Rüdiger …. You make me very embarrassed ….

PlaamooParticipantI got it yesterday via email from Amazonas. Superb Jutta!
