    I recently ordered some Rhinogobius sp. gobies on mail order in the UK as I couldn’t find anywhere else that has seen them in the UK that is near to me (Isle of Wight)….so the shop sent them out but they didn’t know what they were. I have 8 but they all seem to differ in colouration and behaviour413900_305446876255665_1362242264_o.jpg

    Am I right in thinking this is a Zhoui male?

    I’m unsure what this one is….

    And this one, it seems to have very orange/yellow dorsal fins but then changes colour (see pic below)

    Jutta is the expert… but to me they all look like R.diospilus….

    Agree with Mike on both counts. 🙂

    I can not see enough in the photos that are much too vague. If I were to identify duospilus-like, I need sharp photos that show the Branchio Stegalmembran and the gill cover clearly. In addition, the dorsal fin and the tail. Without which you can not say.
    Of the body shape to I’d tap R. cf lungwoensis, but as I said, just one can say that only with sharp photos.

    Sorry Jutta, I took these photos on my mobile phone but I will take some on my digital camera, thanks

    Yes, now they are sharp enough. Looks like Rhinogobius xianshuiensis :-) However, please: such identifications by photo are always without guarantee.

    Wow thankyou for that! That’s really interesting :) Is there any information you could please give about these gobies? Thanks

    Yeah, we really need to sort out some kind of links page or similar. 😳

    Hello, thankyou for that link, it was very helpful. Since I bought these fish, there has been significant developments and not particularly good ones I’m afraid. I put 4 of the gobies in my main tank and their tankmates are full size long-finned zebra danios, galaxy danios, 3 very gentle Laetacara cichlids, a Flying Fox and a Whiptail Catfish. I expected no problems with this combination especially from the gobies but two of them have been terrorising the whole tank :/

    They swim up onto the back glass at the top of the tank and launch themselves into the middle of where the Zebra Danios are swimming, attacking them and tearing their tails!! One in particular has also attacked the Flying Fox who is 4.5in long, who shows no aggression towards it and what really shocked me was it attacked the cichlids, who the other three gobies seem nervous of and normally avoid!! I don’t know what to do as I’m scared that by being stressed, the whole tank will come down with disease!!

    In addition, the goby that does most of the aggression I presumed it to be a female, but it has all the posturing and behaviour of a male now, it’s very confusing! Here is that fish again….P1000732-1-1.JPG

     

    In contrast, my duospilus male that is in the same tank is very placid and spends his time digging out a cave and goes nowhere near the top of the water, he has fought with the fish above but only because it tried to steal its territory….I am now totally confused why the other two gobies would act this way as I haven’t read many things saying these fish are super aggressive to anything other than themselves!

    Normally, these fish are not aggressive. However, I have also never kept this species in such a fish soup. I could well imagine that they will be there very nervous and that they run short on food and therefore try to hunt the small fish.

    You should prefer these gobies spendieren own aquarium.
