in a "surprise bag" with pseudogastromyzon cf cheni (no cheni, but some others) I received this unique one. apparently a female if anyone had an idea ...

Looks very similar to some of my smaller female R. candidianus.

thanks
I've seen this species in the gallerie of aqua-global
http://www.aqua-global.de/Bild...../Rhinogobi...candidianus.jpg

here the species/male shows red parts
http://images.google.ch/imgres.....mgurl=http...%26tbs%3Disch:1
here as well
http://images.google.ch/imgres.....mgurl=http...%26tbs%3Disch:1
at fishbase candidianus looks very different. a surprise?
do your males look like this' and do adult females change?
at first sight no red stripes on the head
with an enlargerged pic yes could be. what surprises me: r candidianus origines from Taiwan and comes in with ps cf cheni
ps: just read they come from china too?

yes. but there are two points to add: duospilus doesn't look like. I have seen them yesterday live. second: as I get my "specials" from the retailer as species to identifie it is unlikely to be a species they have on the stocklist - as r wui (but they know the new name, it's just a way to keep the fish going into the LFS without a break because of changed scientific name).
I hope to have more pics - and some other specimen

thanks cfai
I had a visitor breeding r duospilus. he says: can't be. this one is at least 5 cm long, duospilus are smaller, not so strong and with different pattern and so on. what irritates me: pics of r duospilus show very different species. I'm going to work that out with the threads on perfrd
r candidianus is not far, but I should really have some more specimen. may be some come in on wednesday.
whatever: for my special tank 140x25x25 without heating, s. barbatus and r duospilus are targeted. may be this one too and some n. chrosomus (if I get sound ones) and so on. I think I'll need a second long tank.

I agree with you Charles - will get to work on Rhinogobius before too long. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

some pics.
interesting the orange spot on the head, only to be seen from this side and the orange spots in the ventral and anal fins only in the lateral view
and it really has this wonderful radiant blue
the body shape looks very strong to me. it has no problems to chase the large pseudogastromyzon fasciatus/fangi and sewellia sp away

the yahusikotakia nigrolineta I've got recently are now in the 112 lt tank together with pseudogastromyzon spp and rhinogobius cf candidianus. to my surprise they fit better together than exspected. the rhino female, normally chasing all hillies away lies side by side in a cavern with nigros.
a friend found me a pair of the same rhino species in germany. I'm curious to see the male.
some first pics of the rhinogobius duospilus in the quaratine-tank

I've got the pair. thanks Pascal.
the colouring is a little different: the first female is more grey with steelblue pattern, the pair light brown with steeblue pattern that doesn't come through very clear. the females look lke twin sisters coming from different regions.
I'll try to find the species as r candidianus is out of question if I'm not mistaken.
sizes are: females 5 cm, male 7 cm.
the male shows two yellow dots on the dosrsal fin base

may be
but it looks different to me: the two spots and different dorsal fin colouring
found two pics, one without any further info, one with the contribution sp OR. the species are identic.
but the real rhinogobius sp OR looks diffrerent and comes from Japan.

Torso I'm trying to get my head round all you rhinogobius pic but it looks to me that you have 3 possibly 4 different species.

R. duospilus

R. candidianus (female)

R. leavelli (male)

thanks for the input afroturf
the first female looks like a twin to the second female, apart of the basic colouring. this second female is the one of the pair I've got from Pascal.
so the first one doesn't look like r candidianus to me, but I can only judge it by the pics I've seen in the net.
the pair I've got: the male really resembles r leavelli. but it doesnt have any blue linings in the fins as seen in several pics in the net and in the description of r. zhoui. yellow spots instead of blue spots in the dosal fin
so if it is the same species it's certainly a variation
r duospilus is clear as far as I can judge. but Pascal who has bred them for a long time says, females are missing and that he's got them seperatly as r sp in the trade
what do you think?

Hi all,

Although it comes a bit late, but I want the wrong information given here not leave it at that. I hope you do not take me the evil. I get that unfortunately always in the search results displayed by Google.

The image of torso shows a female of Rhinogobius leavelli :-)
