On yesterday I got back 6 offsprings of my R. giurinus. One lonley male I had before for a long time.

Normally, the offspring are not quite as aggressive as the wild caught. But yesterday, dramas have played in the aquarium.
The two largest males, the desert and the new, fought with each other until the mouth tugging and no one wanted to give up. And as if that was not enough, the two smaller males also began even to fight each other.

Interfere helps probably just not much. They will always start fighting immediately, as soon as I'm out of sight.

So now I have to wait until they agree, who is the strongest. I hope they will not hurt too much. And they are so beautiful in their rage :-)

They certainly are beautiful Jutta, love those long dorsal and anal fins.Smile It is just the pics or do these have a different body shape to most other Rhinogobius species?

No, it's not the pics. Their body shape ist different to other Rhinogobius. If the males are very slim, they look from the abdomen often starved, as thin as they are from there.
But they are really beautiful, right?

This morning, by the way, there was peace in the basin. They have become united, who is the strongest and is now (almost) any on his way :-)
The smaller males threaten a little, but do not bite at least.
Unfortunately, only 2 females are ... I hope that spawn very soon.

I think I'm just getting crazy.
After you've just pointed out the differences in physique, Matt, I have the animals (apparently for the first time) considered me again properly: these are no Rhinogobius! All my animals had never once the characteristic red triangle on the nose, which makes a Rhinogobius.
Now the question is: who ask we to confirm this theory ?

I don't think you're crazy, they do look different. Can email some pics to Helen Larson if ok with you?

Helen Larson is not the specialist for Rhinogobius, Matt. And for my liking sometimes too fast in their judgment *cough*. You may like to do this, but I fear that will bring no really result.

I was thinking the best thing would be to find someone who examines at the DNA? I've got someone who maybe interested. I will write to him once tomorrow.

I asked the ichtyologists, but he has little interest in pursuing the matter. He has sent me a paper (Mitochondrial DNA divergence in yoshinobori gobies (Rhinogobius species complex) between the Bonin Islands and the Ryukyu Archipelago, Japan), which shows the distance of R. giurinus in relation to the DNA to all other Rhinogobius. But more because we will probably never get out.

Then I do not care, they just stick to the Rhinogobius. But I have a clutch again and I look forward to breeding.

The first three pictures show the clutch immediately after removal. 19 ° C, and after just three days no eyes. There should they be actually been hatched.

After 4 hours by 3 ° more temperature suddenly they have all eyes! Fascinating, this speed!

Beautiful photos as always. Cool

Do you think we should continue to call the fish R. giurinus then Jutta?

We are left with no other choice, Matt. It is the vailde name and we will probably not get another.
I am in September in Stuttgart at Datz forum. There I get another opportunity to speak with various biologists and ichtyologists about this topic. Perhaps there is indeed still a solution.
