lately I got some sicyopterus specimen. on the list as s. longifilis. could be s. griseus from India, imported by Reuter, Germany. as the patterns are very variable and changes within seconds not uncommon, it's still in question if it could be s. griseus as presented in the last Amazonas-Magazin. they are large - 8.5-10 cm - and very hiding. good shots are rare. specially the large dorsal fins are not to "catch".
any ideas?
here some pics

Now I'm really jealous Charles!n I love these fish! /wub.gif" style="vertical-align:middle" emoid=":wub:" border="0" alt="wub.gif" /> I've been hoping to find more ever since my last one decided to go exploring. Keep the tank completely covered! After settling in mine were very outgoing and personable. Great plant cleaners! Sorry, no help with ID.

Very nice Charles, are they definitely from India? Could also be one of the many forms of S. lagocephalus?

Here's a bona fide, wild-collected S. griseus. Not the same methinks.

What are the differences that your seeing Matt? In my very limited experience, the color changes in sicyopterus were crazy! From virtually no color/patterns at all, to bars-spots-green-grey- irrideecent fin edges!

Beautiful fish, I'm a great fan of my 3, all of which were given to me free as rescues from the LFS. They love to consume freshly growing algae, and I have one that will take prepared foods such as algae tablets. I know that Beta on Petfrd had some that were feeding on bloodworm. As Jim says, the colour changes are rapid, and they are mildly territorial. I've haven't been able to identify them down to species level, I just call them Sicyopterus sp. /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> How many did you get Charles?

Was it Hayath that had fry but they didn't survive for long?

Body pigmentation mostly. Hayath's fish doesn't appear to have a dark lateral stripe unlike Charles'. Dorsal surface patterning is different too. I could of course be completely wrong. /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" />

The pics posted by Torso are definitely not of S. griseus.

Yes, Hayath's fish is a wild specimen collected from Nilambur, Kerala. I had given him about 3 fishes from that batch. I guess he should still have them.

Here's my crazy F1 juvenile video. : )

Thanks for the confirmation Shankar! So you bred them?

Yes, Matt, they had spawned themselves. I didn't do anything. /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" />

Since, I had already bred Stigmatogobius sadanundio many times, I was willing to give it a try on the Sicyopterus. I retained a gravid female and the alpha male and another sub-adult male as a dither. A few months later I saw the above lone surviving juvenile creeping out on the tank wall for algae. Perhaps, the strongest fry survived to adulthood.

And, it was Vyas who had Sicy fries.

Thanks for the reminder /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> They didn't survive though, did they? It's times like this you could do with Petfrd still being up /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> I'm sure Tyrano had some success too, perhaps he posted that on here?

Tyrano's fish ended up being Marosatherina ladigesi. See here (from towards the bottom of page 2) and from post 157 here.

It's pretty amazing, don't you think, that a species with an amphidromous breeding cycle can produce young otherwise. Evolution???

Maybe some land-locked populations breed only in freshwater as in Rhinogobius?

Dont think our Sicy are found in any land-locked water bodies. Perhaps, I may term it as 'adaptation' of desperate fish. : )

Hi Torso.

The distinction of Sicyopterus is very difficult for me.

I'm reserving Japanese S.lagocephalus.
Sicyopterus genus which ranges in Japan is S.japonicus and S.lagocephalus only.
Therefore it can be identified from habitat information.
http://forums.loaches.com/view.....pic.php?f=...10&start=30

I noticed the one which seems to be the feature of S.lagocephalus recently finally.
Their body pattern is very variable, but 3 big white spots sometimes appear in a tip of nose.

3 white spots in a tip of nose were found also in your pictures.
Your Sicyopterus seems akin to mine.

This feature isn't manifested in S.japonicus and S.sp (Mountain-Rock-Goby) at least.

The same feature has also gone out to Sicyopterus.sp from Indonesia.
The distribution of S.lagocephalus is very wide.
Probably I think that my one from Indonesia is S.lagocepharus. /blush.gif" style="vertical-align:middle" emoid=":blush:" border="0" alt="blush.gif" />

hi odyssey
tremendous threat you have there`...
the information about the orogin is confirmed: they come from India.
the pics with the "fighting" colours make me think that it s not lagocephalus. mine look different in that situation. won t be easy to take pics
