Does anyone here have info on this species per chance? Specifically, aggression level and breeding. TIA.

Hi Mike,

territorial and aggressive should not be taken too literally. For people who have no experience with Rhinogobius whose normal social behavior certainly looks very aggressive, but it is really rare.
Aggressively Rhinogobius would mean that they actually bite or pull at the mouth. All other actions such as permanent hunting or "wipe out the other one" is at Rhinogobius no aggression, but a game.

We have not as yet received definite R. cliffordpopei. All the animals who had been designated as such turned out to be Rhinogobius leavelli or R. rubromaculatus var. yellow.
But I do doubt that this species is more aggressive than the other species. The only Rhinogobius who have been bitten by another real, were R. giurinus and currently I have some wild caught male, which behave very civilized. Again, the behavior is apparently of the pool facility and from the keeping.

Hi Jutta,

Thank you very much — I hope it is not too late! I cancelled the order yesterday (I'm a bit paranoid here, after a bad guirinus experience), trying to restore it now.  If the fish is not a cliffordpopei, it ultimately would not matter, I simply would like 2-3 more "safe" rhino species in the fishroom. A bad photo of the fish is here:

Does not look like R. rubromaculatus to me (this is actually the species I'd like most)…

Yes, Mike, this should be a R. cliffordpopei, but it could be just any other Rhinogobius. The pic is really bad.

So, you've made some experience with R. giurinus. Yes, this could be shocking Confused They are mostly very territorial. Amazingly only the wild caught, my offsprings live with other males in absolutely peace. At the moment, I got 2 wild caughts and one of my offsprings and they are peacefull too. I'm amazed.

 

Good luck for restoring the order. I hope, we get better pics from you :-)

Pic enlargement not showing for me?

 

Why don't you go for the r. zhoui Mike? Have you seen them in person/fish? Stunning!!

Yes, Jutta, if I get them (50% chance right now, I did re-ask for them) you will see better photos. The shot above is from the vendor, and while I saw the fish in person there was no way to take a better photo: the tank is too dark and therefore the fish is not well colored.

As for guirinus: yes, it was shocking, especially that the males killed the females too. :(   I hope you are right about the tank raised fish being milder…. I'm a bit doubtful because what I saw was that the younger fish is mild, but once they reach certain size they get homicidal…. maybe your offsprings are simply too small to reveal their true evilness? :P

Why don't you go for the r. zhoui Mike? Have you seen them in person/fish? Stunning!!

I probably will eventually, at the moment I favor cheaper fish…:blush: $75/pair vs $25/pair. I did see them in person…ok… to be honest,  I find r.rubromaculosis prettier, and of course e.caeruleum (and most of etheostomas) are way prettier and more entertaining than any rhinogobius…

Pic enlargement seems like a bug, try right mouse click on the image followed by "View Image", or see the images on Frank's page:

No, Mike, the giurinus-male are adult and are breeding at the moment. My offspring are from July 2011. I've never seen, that they kill females. There must be something which could not have been in regulation.

The R. zhoui on Franks site are very young and and far from fully grown. Have you seen my pics, Mike? These are males, which are about 1,5 to 2 years old. Then they get just their real color and beauty. They grow slowly and require approximately 1 year in order to develop properly, and then once a year until they are fully grown to full width. But they are really beauties, above all, when you see them interact.

If all goes well and looks the way it is just emerging, the breed will run this year perhaps a little more successful. Maybe the price will then adjust down a bit finally.

The pics from R. cliffordopei show the right species. I'm curious if you have them.

The r. zhoui that I saw in a shop tanks were 2 males & a female in a small tank. The males were going at it and they were amazing. I'm going to have to find money and space for them at some point.

Never see r. rubromaculosis or any of the etheostomas in person. Pics I've seen of e. caereleum are stunning!

Let's go with the hijack :P

 

Frank had R.rubromaculosis last year… I passed on them, not knowing at the time what to expect from all these new rhino species and being afraid of another guirinus episode.  As for E.caereleum, they are just as stunning in person (I have a group of them), and I've never seen them arguing…  I picked up a new pair in the fall at a club auction (the seller caught them himself)… 3" fishes, I never saw a 3" female before…not colorful, of course, but still very impressive.

The strangest fish as far as eating habits go: about three times out of four she refuses the food (even bloodworms), but on the fourth time she would gorge herself (everyone else in the tank eats every time and begs for more). Since this has been going for six months now, it is probably not a disease…. only weird.

I need to clean up their tank (cyano :( ) and ask Tao to take some photos.

Anyway, darters are not expensive or rare… if you have space, grab! I'm seriously thinking about an E.fusiforme group now….never kept them and they are different…

Mike, the name of the Rhinogobius is "rubromaculatus", not rubromaculosis… this species is not existent :-) I don't know, where you get this name… but it is for me very important, the gobies with her ​​real name be mentioned, because otherwise the confusion is getting bigger (this really applies to all fish species).

^LaughYou had it correct in your first post. It is easy to stray with some of these names. I do it regularly.

I think we all agree Jutta on the importance of keeping them correctWink

Between the first and the second post I did the water change on G.maculosus fry tank (really) Laugh These things hybridize in unpredictable ways.  Embarassed

I thought wui & duospilus were synonymous? Pic 4 may be r. leavelli??

In the literature yes but it still seems to be accepted as different. Certainly the fish in the hobby identified as them are.

 

The 4th pic was in with the szechuanensis so I assumed it was just a female of that species?

 

Identifying these Rhinogobius is a nightmare

The fish on the last picture is Rhinogobius cf. nandujiangensis. On second could be a Rhinogobius duospilus. Looks like a female, but ther are red stripes on the Branchio Stegalmembran.

Rhinogobius wui = Rhinogobius duospilus, they was renamed 10 years ago.

 

On the 4th pic, I thought too, that is R. leavelli, but they lack the orange spot on the tail fin. But it is definitely not R. szechuanensis. But I have no idea, what it could be.
