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.

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 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

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…

 

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!

 

Sorry to hijack your thread

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).

^You 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 correct

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

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.
