I add images of two kinds of Sicyopterus inhabiting Japan after a long absence.
These are Sicyoputerus japonicus taken in the middle portion of the Izu Peninsula of Japan in the fall of last year.
On the other hand,these are Sicyoputerus lagocephalus that live in the most southern part of Okinawa Japan.
Because the characteristic of the species does not yet appear in the fries, the distinction with S.japonicus is difficult.
However, it is more likely to be S.lagocephalus when I think about a season.
I can distinguish S.japonicus from S.lagocephalus easily.
S.japonicus has a lateral stripe design without disappearing since the age of a child fish.
The design is a pattern such as "\\\\\\\ //////".
S.japonicus does not seem to change most of the designs of the body, but S.lagocephalus can change a color of the body busily.
The following photo is childish fish of S.japonicus which just went up from the sea to the river.
This is a 2-year change of the same S.japonicus individual.
The next picture is a figure three years before and the recent figure, same individual of S.lagocephalus .
S.lagocephalus can completely delete the pattern of the body.
S.japonicus and S.lagocephalus.
S.lagocephalus and Sicyopterus.sp(Mountain Rock Goby)
Though S.lagocephalus change the pattern of the body, a specific pattern appears.
The scientific name "lagocephalus" seems to mean the head of the rabbit in Greek.
May you find the white pattern like "a head of rabbit" in the tip of nose of S.lagocephalus?
Or the big white pectoral may be likened to the ear of the rabbit.

I visited some rivers of Izu Peninsula last month and took many photos of underwater.
I want to see waterfall-climbing scene of Sicyopterus japonicus and visit the river of Izu Peninsula for five years, but it was only once that I was able to watch it.
Sicyopterus japonicus in Izu Peninsula of October, 2013.
A video clip is in youtube.
Because they eat an adhesion alga, both S.japonicus and sweetfishs do a territorial dispute each other.
Sicyopterus japonicus in Kii Peninsula of June, 2012.
A video clip is in youtube.
Waterfall-climbing scene of Sicyopterus japonicus in Izu Peninsula in 2009.
Unfortunately it was only this time that I was able to watch their waterfall-climbing.
In this district, this age had little rain in particular.
Possibly their waterfall-climbing action may be related to a lack of rain.
I edited a former video briefly and uploaded it newly this time.
Though it is not mine, I introduce the splendid video which HORIBA provided.
I did the expedition travel to a Ryukyu area that was the subtropics climate in the south end of Japan last December.
Unfortunately there are few pictures of Sicyopterus genus.
I traveled to Amami-ohshima that was a southern island of Japan last month.
And I took lot of pictures of Sicyopterus japonicus there.
The youtube video that fries go up in a river from the sea
The fry which just switched over from seawater to fresh water.
The fries go up in crowds to the upper reaches.
The individuals which grew up drift the bottom and graze algae.
I traveled to the Micronesian Pohnpei Island in July I visited three rivers and waterfalls in Pohnpei island and was able to encounter Sicyopterus lividus.

It may be a young fish of Sicyopterus lividus
In this place, there was Sicyopterus lagocephalus
wasserscheu stated that it was like Sicyopterus cynocephalus in this thread before.sj861008 wrote:Do you know the name of it Mountain Rock Goby？and How did you get it？i think it is Sicyopterus punctissimus or Sicyopterus fasciatus，do you think so？
I think so, too.
This Sicyopterus rarely arrives at the aqua shop as from Indonesia.

Your Sicyopterus.sp seems to be neither S.japonicus nor S.lagocephalus.sj861008 wrote:I got two last year with the name of Mountain Rock Goby,Do you think it's the same as yours？
I think that's probably the same species as "Moutain Rock Goby".
You can display images directly if you sandwich the "URL" of the image in " "
For example as follows
↑ I'm sorry that it is not seem to be possible in your web site.
Hi sj861008!sj861008 wrote:This one of mine，Sometimes the first dorsal fin has a spot，and sometimes not，Does your fish also like that ？
I have not seen such change in Sicyopterus.
About direct indication of picture.
It doesn't seem often able to indicate a picture of your site directly.
I'll apologize for having told the wrong means.
It's sometimes made indication directly, but it isn't almost indicated.
