Stiphodon is distributed over only most southern Okinawa in Japan, but loaches hardly inhabit Okinawa .
Therefore, it is impossible to watch Stiphodon and loaches together in a river of nature.

So, in nature Stiphodons usually live by themselves, without other species around? That's cool :wink:

Thank you for the link! It's very useful :) Now, I'll just have to decide how many Sicyopterus lagocephalus, Sicyopus zosterophorum, Lentipes armatus and Stiphodons can be in 180l tank (if it's possible)... Any ideas? :)

Hello everybody! I've been an avid follower of this forum for quite sometime now and I am really amazed by the amount of pictures and informations being shared in here. Thank you Odyssey for starting this forum and for sharing your amazing pictures and videos and also for the useful links. In the following days (if my schedule permits and if everybody is okay with it!) I will be sharing my own Stiphodon pictures. These pictures were taken in some of the rivers along the eastern coast of Luzon, Philippines. Keep up the good work everybody!

Wonderful, I'm looking forward to seeing your photos.
I think our generation aquarist to understand that you share our knowledge because we do not know how to do and the future of our fish.

Many habitats are in danger because of the needs of humanity and especially of those errors.

Hi shadowbane, welcome to LOL!
Thanks in advance for your help.

I look forward to pictures of your Philippine Stiphodon, too.
S.olivaceus should be distributed over the Philippines. I am glad if I can watch it.

By the way, I traveled last month to Taipei.
I came to like Taiwan very much.
I think while being close, I go to Taiwan again.
I'd like to take a picture of Stiphodon and Sinogastromyzon at a Taiwanese river next time.

I am sorry that some of my photos are off-centered and are not clear. Its difficult to take their pictures because they move a lot. Anyway, I was hoping to take better pictures next time.

By the way Odyssey, we have a lot of Sicydiinae (Sicyopterus, Stiphodon, Lentipes) and Sinogastromyzon and Hemimyzon species here in Taiwan. But in my lab, we only research Sicydiinae and other amphidromous goby species like Rhinogobius, Glossogobius, Awaous etc. Also my lab mate took a lot of Stipodon/Sicyopterus pictures from the rivers in southern Taiwan. I'll try to ask him for some copies.

Thanks everyone!

I'm in heaven, it's a wonderful story.

You saw eggs Stiphodon?
Could you go back and lift some stones to see if they lay at this place.

You could gps coordinates of the location and parameters;
You have observed strange behavior and Stiphodon eaten other things as algae?

What are the species that lives with Stiphodon?
How many species of Stiphodon you saw?

What is the egg that is in the foreground?

Thank you I'll stop there, I expect your first response ...

Excuse me for my English, I'm French.

Hi shadowbane!
Thank you for showing pictures of splendid Philippine Stiphodon.
They are very interesting.

I went to Philippine Cebu two years ago and have photographed Stiphodon.
I was able to watch only S.atropurpureus at the place.

However, several kinds of Stiphodon seems to appear in your pictures.
If Stiphodon is the study of your laboratory, probably you should grasp the scientific name.
I want you to clarify a scientific name of Stiphodon of your pictures.

Following Stiphodon was introduced by this thread before.
This Stiphodon.sp could be seen now well recently in Okinawa in Japan.
It's said that this Stiphodon was released as a new species at last year's Japanese ichthyology meeting.

http://tsudoi-company.com/photogallery/ ... n_sp.1.htm
http://island.geocities.jp/churamizu/Stiphodon-sp.html
Was there this Stiphodon in your pictures?

The distribution of S.percnopterygionus is very wide, but a mention to be distributed over the Philippines is not found one more.
Does S.percnopterygionus inhabit the Philippines?


Hi all!
I hope for providing technical assistance to all of LOL.
I see only the URL text of the link without a image of shadowbane being displayed.
The person understanding a cause please give an advice.
Thank you.

Hello everybody! Sorry I wasn't able to answer your questions as soon as possible because I have been very busy with school and laboratory works these past few days. Anyway, can somebody please help me fix this problem that I have regarding the posting of my pictures. As most of you must have noticed, its not properly displayed. Can't seem to get it right. This is so embarrassing. Please Help!

Hi Tyrano34! I'll try to answer your questions the best I can.
1. The eggs that you saw attached on the rocks were in fact the eggs of nerites or neritina, a gastropod mollusk that occurs in fresh, brackish and sea waters. Some neritina species, like the ones endemic to Hawaii, have an amphidromous life cycle like the Sicydiinae (Sicyopterus, Stiphodon etc.) gobies. The adults of the amphidromous neritina species will spawn in freshwater and their newly hatched larvae will be carried by the downstream river flow towards the sea where they will spend several days, weeks or months (depending on the species!) drifting with the oceanic currents before migrating back to the river mouth to inch their way up to the freshwater habitats they will occupy as adults. This kind of life cycle is also observed among some species of gobies (Sicydiinae, in particular), shrimps, crabs and mollusks.

2. As for the Stiphodon eggs, I haven't seen nor observed it in the wild.

3. Unfortunately, I don't have any GPS coordinates or other parameters recorded when I took these pictures but I love to make some detailed records next time. Anyway, I am very familiar with the place because my family lives nearby and I frequent this river when I was a kid so I can always go back and go check on them.

4. Based from my observations on the same river system where I took these pictures, a lot of other amphidromous and non-amphidromous goby species co-exists with Stiphodon like Awaous, Eleotris, Glossogobius and Rhinogobius etc. but I have never seen them grouping together with Stiphodon. This is because some of them are carnivorous and are a little aggressive (particularly the Eleotris sp.). They're relatively big size could easily scare the smaller Stiphodon species. Its a common thing to see, whenever we collected these carnivorous goby species, smaller gobies or shrimps inside their stomachs.

5. Stiphodons like all of the other members of the subfamily Sicydiinae, are grazers. Meaning, they feed on algae growing on the surface of rocks or woods. They have a specialized set of teeth that they use to scraped off the algae on the surface of rocks or woods.
I hope I have satisfied your questions Tyrano34

Hello Odyssey! I am so sorry that I haven't fixed my post yet and I am very happy that you like my pictures.
Nice to know that you've been to the Philippines before. Been to Cebu a countless times but unfortunately, I wasn't able to check their rivers there.

You are correct to say that I have several Stiphodon species in my photographs. I have one male percnopterygionus in nuptial colors that is very difficult to follow and photograph hence it is always out of focus in all of the pictures that I have taken for it. I have also male atropurpureus. As for the female Stiphodons, its rather tricky to assign them to a specific species because as you might have known already, the females some Stiphodon species (atropurpureus, elegans, imperiorientis and percnopterygionus) look very similar save for some subtle differences and is rather difficult to assign to a species without any detailed morphological examinations. But considering that imperiorientis is only distributed in Japan (its supposed distribution in southern China and eastern Taiwan is not yet verified!), that leaves atropurpureus, elegans and percnopterygionous to be the possible female Stiphodon species in the pictures. Female percnopterygionus and atropurpureus are distinguished from one another based on the presence (atropurpureus) or absence (percnopterygionus) of black dots on their anal fin. As for your question if percnopterygionus occurs in the Philippines, I am certain that they do considering that they can also be found in Micronesia (Guam and Palau) so the possibility is high.

Thank you very much everybody!

Hi!
The male female ratios of sold Stiphodon are different by a species.
But only my feeling, the impression is as follows.
S.percnopterygionus is 1:1
S.atropurpureus is 1:1
Blue-moon is 1:1
Rainbow-color is 20:1
Orange-fin is 20:1
I do not know why there is a difference in the number of males and females.

The frequency of the water change for twice a month.
I change a one-third of the gross quantity every time.
The quantity is approximately 20 liters.

For my impression, most Rhinogobius is violent-tempered.

Stiphodon is a part of the a variety of fish species in my water tank.
Picts of the fish which can coexist with Stiphodon peacefully

20 males per 1 female in case of Rainbown color Stiphodon? :shock: I have (well said, I had) two Rainbown color males per 3 females but the dominant male did not stop to pursue the smallest, and finally I found it dead under a stone (perhaps for not be able to feed). I think that the problem is I had only a few stones where it can hide, today I have put more stones in the tank. What do you think odissey?

I also have Rhinogobius with Stiphodon, but in my case they doesn´t fight between, just mark their territory
