Hi Racoll, Why are the black, and brown-spotted phenotypes considered conspecific? ..the blunt answer I could offer would be because they can "change" their coloration quite a bit, at least according to my observations at importers. In this fish (as well as in L 351) it appears to depend a...

Hi, note also that the original L 350 publication by DATZ came with a mouthshot (see the Matt´s link). And while I concede that that might be hard to see with such a compressed PDF-file, the original picture clearly shows the "non-Panaque" type dentition. So I am pretty sure that what we c...

Hi Racoll, sorry for the confusing post. Daniel (hopefully) put it more understandably. My main point was, that L 351 cannot be Hemiancistrus pankimpuju because L 351 has the typical dentition of Panaque/Panaqolus, while H. pankimpuju has more numerous, two-tipped teeth. This same type of two-tipped...

Hi Racoll, As I see it H. pankimpuju does not have an L number, L350 is P. nocturnus, and L351 would then be P. cf. nocturnus, if these proposed morphological differences stack up. ..but "the fish formerly known as L 350" has a non-Panaque (or Panaqolus) dentition. Teeth are more abundant ...

Hi Shane, the "problem" with Hypancistrus is, that it appears to be possible to produce virtually any cross between those forms. And (to my knowledge) none of them turned out to be infertile (which, admittedly, has not been checked thoroughly in most cases). The best documented cases are f...

Hi,

breeding of a Spatuloricaria sp. from Peru has been reported by Mike Hemmann in the (German) magazine "Amazonas", Issue 12.
The article appears to be freely available here:
http://www.amazonas-magazin.de/AMAZONAS ... 370.0.html.

Hope that helps,
Sandor

Hi, the fish from Rio Tapajos is L 97! No matter what the collectors say, L 282 was introduced as being from Venezuela and therefore, only fish from that country "can" be termed L 282 (smuggled fish does not count!). Cheers, Sandor P.S.: There is also P. sp. "Alenquer" from the T...

Hi,

if this one came from Glaser declared as L 180 very recently, it is highly likely to be L 213 just as mine are.

Cheers, Sandor

Hi,

L 410 is known for its comparatively very large and deeply emarginate caudal fin.

Neither of these two criteria is visible in the pictures posted here, I am afraid..

Cheers, Sandor

Hi, notwithstanding any ascertion that, like all systems of classification trying to group dynamic systems without clearcut differences, the L-Number-system is neither perfect nor without contradictions, I believe that most frustration with it actually stems from inaccurate application than from the...

Hi, I am certainly more on the splitting side of life. Though I currently try - partly because I am predominantly dealing with as-yet undescribed variants - to avoid the term species (or put it into quotation marks). On the practical side of fish keeping I go by "if it looks different, consider...

Hi, strongly reminds me of what I know as Hypostomus sp. "Rio Sao Francisco": http://www.forenfotos.de/albums/userpics/10031/Hypostomus_SF_1_klein.JPG Sorry for the crappy pic, but it´s the only one I have showing the "settled" coloration. There were also featured by Aquarium Gla...

Hi, I am a different size to a African Pigmy a different pattern to a Hmong from the planes of jar in SEA and a different shape to a person with dwarfism am i a different species? for purely ethical reasons, this is not a valid question. When it comes to humans, the pure biological reasoning must st...

Hi, So hanging an L number on every morph or variant is crazy. I´m sorry, but from this (and your answers above) I gather that you did not fully understand the concept of an L-Number. An L-Number is a picture of a fish (which should be not yet scientifically described and "sufficiently" di...

Hi, I do agree that the description of P. titan fits nicely with what we knew as L 418. On second look, however: what do we think of the distribution? L 418 is known from Rio Huallaga, a southern tributary to Rio Maranon, which in turn unites with Rio Ucayali "flowing north" to form the Ri...

As an addition: I initially overlooked Chaetostoma aff_milesi , which is a C. milesi type of fish, but without spots in the caudal fin. That is supposed to resemble C. milesi more closely than the other type of fish. As a downturn, Chaetostoma aff_milesi is from Venezuela, while C. milesi is describ...

Hi, I finally "found" the time to add the latest L-Numbers (L 443-L 447) to the eLog. And, put bluntly, it´s one of those cans of worms.. :beardy: As for now: The L-Number L 445 has been issued to a fish that is depicted in the Wels Atlas 2 as Chaetostoma sp. "Villavicencio I". T...

Hi, Ancistrus sp. "L 182" and A. sp. "Rio Ucayali" are clearly discernible as juveniles: Ancistrus sp. "L 182" has - at least up to 6-8cm - a reddish-orange margin to the caudal and dorsal fin and yellowish spots. Ancistrus sp. "Rio Ucayali" on the other hand ...

Hi, ..I sense a certain amount of demand for this fish (those posted here certainly are some).. :foggie: And while it definitely is off-topic: I could raise one or two batches for the next L-Numbers Days: http://www.forenfotos.de/albums/userpics/10031/Hypancistrus_L70_3tage_pcf.JPG Might give us a c...

Hi,

Pic 1 looks like young Spatuloricaria.
Pic 2: agree with HH.
Pic 3: same as Pic 2.
Pic 4, 5 and 6: Spatuloricaria and Crossoloricaria again.
Pic 7, 8 and 9: Sturisomatichthys sp.

Cheers, Sandor

Hi Mats, "problem" with the fish in the eLog under L243 is, that they don´t look like "typical", adult L 243. Hence the link to the other, more typical pictures. They are not L 80 (too large) or L 49 (too colorful), otherwise, at least a country of origin would be helpful. Cheers...

Hi,

this fish makes me think of L 243 (http://www.l-welse.com/reviewpost/showp ... roduct/258).

Cheers, Sandor

Hi, several species of Garra have been "naturally" spawned in the aquarium. Have a little trouble to come up with a decent "proof", since loaches are not really my center of interest. But in an article available online in DATZ (http://www.datz.de/Garra-rufa---Eine-Bilanz-Saugbarb...

Hi, there´s gonna be some additional information in the eLog in due course. Meanwhile you can (all those capable of reading German, that is) find my contribution here at DATZ . Should be publically available. As to the known distribution: the fishes now given the L-Number L 452 were collected some 2...

Hi,

I guess you are referring to Ancistrus sp. "Blauauge" (=Blue eye).

This "species" has been found to be identical to Ancistrus sp. "L 88" some time ago and the pictures of it can be found under the latter entry in the eLog.

Hope that helps,

Cheers, Sandor

Hi, If a Scandanavian guy has a child with a girl from Sudan , totally diferent looking people are the children bad? considering this example from a different perspective, I would state that you can only give this example because until very recently, our species consisted of several populations that...

Hi,

Would be nice to have a ventral view of L377.

You can find one here:

Cheers, Sandor

Hi,

the specimen pictured by Ivan Mikoji was caught somewhere in the Rio Orinoco drainage, Venezuela.
Hope that helps!

Cheers, Sandor

Hi,

..darn, that was typed too hasty.
The last sentence is supposed to read:

The Oxyropsis are lacking the (hardly visible) adipose fin of the Hypoptopoma and are flatter and broader, as opposed to the Hypoptopoma.

Hope that makes sense now..

Cheers, Sandor

Hi, they appear to be an Oxyropsis species, based on body shape. These also come from Peru, and my current "best guess" is O. cf. wrightiana. I had a comparable case here: Ordered a group of fish listed as Oxyropsis sp., and got 8 H. gulare with 2 actual Oxyropsis "mixed in" (ori...
