    I would say, it is not R. leavelli. The first pic looks like Rhinogobius rubromaculatus yellow. But not really. Only similar. I don’t know, what species it is. But definitely not R. leavelli. The eggs are too large.

    It is always a very bad idea, to keep only a pair of Rhinogobius.

    An even worse idea would be, to put the female alone in a tank. She would very quickly become apathetic and die. Rhinogobius are group fishes that are highly dependent on their social contacts. To keep them alone, would be torture.

    Late, but hopefully not too late :-)

    I will today receive a group Schismatogobius. What species exactly, I do not know yet, there seem to be several. So I’m just tripped over this post. :-)


    I have until 2 years Schismatogobius marmoratus kept, which have multiplied completely unnoticed in my aquarium. I have inserted 3 animals at the end and 5 found :-) Unfortunately I have not notice anything, so I can not say more than that they breed in fresh water.

    Hi Mike,

    sorry, I was a long time not online.

    You can feed them anything, you want. They eat everything that fits their mouth :-)

     

    Concrats! What takes long is worth it :-D

    Hi Mike,

    congrats for the rubro-fry! Things come to those who wait well. :-)

     

    P. novemradiatus can handle seawater-salinity. No problem, because whose main habitat is the coastal.

     

    But how big should the aquarium be to make the P. cyanodorsalis sufficiently large swimming space?

     

    For the Mugilogobius I have no idea for a particular species.

    Unfortunately, that’s not such a good thing overall. Periophthalmus novemradiatus want to live in large groups. They need the vicinity of their fellows, to feel safe, very urgent. If kept alone, they are very insecure, very quiet … and not live long.
    It is sad that the animals are sold so.

    Hi Mike,

    some Mugilogobius may correspond with your criteria. And some sea ​​water gobies too.

    Knight gobies are very, very, very snappy. This you can, except with blennies and pufferfish, with nothing socialize.

    First the red stripes on the Branchiostegalmembran are seven, slightly interrupted (Total 17 spots).

    (Paper) The colour in alcohol is gray with five broad black cross bands

    At this species there are seven.

    Particularly striking is the red-colored caudal fin.

    Yes, Matt. Only R. duospilus is described. But, if you look at the paper, you will see, this is never a R. duospilus. I’m looking for a biologist who has an interest in determining these animals.

    Jim, only for Mike! Kiss No, I’m joking, of course you can like them too Laugh

    Meanwhile, I’m pretty sure that the animals are shown, are no R. duospilus, but R. sangenloensis. Probably a location variant from Hong Kong, because they are actually native to Hainan. And of course I have a few females. Unfortunately, only 3 of 11. But I get some additional in May.

    Mike, in Germany it has become common to speak of cf. Paskai red neon or simply “Paskai”. And gertrudae be distinguished in ARU II, ARU IV and aquarium strain. This is internationally often confusing, I know.

    With the zhoui I currently have likewise with or without a net quite poor results. This could be because the winter rest has failed. I suspect the results will be better again in the summer.

    I’m not sure, what they are, but I think, it’s Rhinogobius sangenloensis.

    This is really strange. I have in the gertrudae a pretty balanced ratio, and at the Paskai there were more females than males.
    What conductance you have in the tanks?

    Tomorrow I get Rhinogobius from Hong Kong, Mike. Supposedly duospilus, but it seems to be a different species. If they are there, I’ll show you photos. Beautifully!

    In re Mellis sex ratios: finally have the results. Despite what my friend was saying, essentially 50:50 split.

    Very good result! With me it was 70% male, 30% female. But better than nothing :-)
