Hi Milton,

would you happen to have a copy if that..?

Thank you,
Sandor

Hi Eric, In my opinion and as far as I am aware of the back story what is sold as L144 is indeed a mutation of the common bristlenose. The fact that it shows no spots should be a side effect of the specific mutation, depending on which pigment cannot be produced. I would expect albinism and xanthism ...

Hi, Your "female" is not a Panaqolus! Looks more like some kind of Chaetostoma.. So, even if it is a female, they won't breed because they're not even of the same genus.. Cheers, Sandor P.S.: the male indeed looks like a male. Can't make out the species, but it indeed looks like some kind of ...

Hi,

I believe Daniel is referring to the fact that while being a distinct local variety that should not be mixed with P. brevis, L205 is at least scientifically not a distinct species.

Cheers, Sandor

Hi,

Both male based in the tentacle growth on the top of the heads.

Cheers, Sandor

May I have a copy of this one, please?
[edit]Thanks Daniel![\edit]

..and the best way for you to "help" is to not bother them (yes, I know that's extremely hard!).
If you can, ignore the tank for two, better three days..

Hi Jacqueline, Short answer: there is none. L600 isn't a "valid" L-Number, but was invented by some seller to make the real P. leopardus appear more interesting (still today, a fish sells better if it has an L-Number, almost regardless of what it looks like).. So what you find advertised as "L600 ...

Hi,

That's the bred black variety of Corydoras schultzei (if I'm not mistaken still technically a synonym of Corydoras aeneus).

Cheers,
Sandor

Hoops,

There are a few pictures of young fish taken by Karsten S.
He is probably willing to also provide them for PCF..

Cheers,
Sandor

Jools, Unfortunately the L-Welse.com server is down right now and my literature is still in storage in Germany, so I have to work from memory. But I *think* there are some rather good pictures of LDA-81 under the trade name Peckoltia sp. "Manaus" available (and as soon as L-Welse.com works again I ...

Hi,

Sorry to disappoint you, but LDA81 has been spawned for years in Germany (over several generations).
Still, no small achievement, so congrats!

Cheers,
Sandor

Hi,

Just for the sake of completeness: number one could also be L52.
Pretty difficult to tell apart on pictures.
Good thing for you is that there's practically now difference in keeping L52 and L168.

Cheers,
Sandor

Hi,

that likely is Ancistrus sp. "Rio Ucayali", definitely no A. hoplogenys (markings in the fins are wrong, base color is off, "net" markings on the head are not present in A. hoplogenys).

Cheers,
Sandor

Hi,

looks like the fish formerly known as Pseudancistrus sp. "L 67" is now known as Pseudancistrus asurini.
Pseudancistrus kayabi on the other hand reminds me a lot of L321 (that one I´m less sure about, though)..

Cheers,
Sandor

Hi, the Super-Red bristlenose was first line-bred from the calico form of the common bristlenose by a German hobbyist. As is the way with the common bristlenose, they are pretty fertile and as soon as the pure strain got introduced into the market, it spred pretty quickly. A long-finned variety got ...

Hi, AFAIK, the origin of C141 is unknown. I just had a quick look at the original introduction of C141, and no location is provided in it. It is presented as an occasional by-catch which is frequently erroneously ID'ed as C. ornatus. C141 is supposed to have the markings of C. ornatus, but with a ...

Hi,

with those pictures I actually agree with Jools, it IMHO is something like H. debilittera.

Cheers,
Sandor

Hi, I´ll have to admit that I´m a little surprised I actually did remember my camera (or, more precisely, the request here), but nevertheless.. http://www.l-welse.com/gallery/displayimage.php?imageid=13994 One adult, nuptial Peckoltichthys bachi. Started to grow the odontodes some 3-4 weeks back. ...

Hi,

I would add Peckoltia caenosa to the list of potential candidates..
But to get a better ID, you´ll have to provide better pictures!

Cheers,
Sandor

Hi, well, I am not a biologist, so perhaps a geneticist can better explain (or perhaps even explain why my explanation is wrong). And after looking it up again, I realize that the english word is actually xanthism.. Those are different kinds of mutations: leucistic individuals do not have ...

Hi, Did you buy them directly from German hobbyist breeders who have a known record of provenance that the fishes descended directly from a very small number of wild-caught Paraguayan stock animals? ---> "Yes": Congratulations, your fish is real L144. ---> "No": Your fish is the yellow colour form ...

Hi,

So then he would have to pair off the male to one of the more promising female offspring?

yup, that would be the start..

Cheers,
Sandor

Hi, the big problem with this group of fish is that there is a vast amount of people that believe they have L180, but only a tiny few of them actually have them.. And only the firm knowledge of the collection location of the actual fish will allow for a 100% ID. From the body shape alone I believe ...

Hi Jac, just a little more on that topic, realizing that a picture probably says more than an elaborate description. Only problem is that I need two hands to separate eggs and a third to take the picture (so I´m sorry for it being slightly out of focus).. http://www.l-welse.com/gallery/displayimage. ...

Hi, @Marc Interesting to read that others have the same kind of experience with Pseudacanthicus as I did. And I haven´t tried it with L114 yet. Good luck with raising them! @Jac I use a 10mL syringe with a piece of pretty old 6mm airline attached. That airline is almost not flexible anymore, which ...

Ron,

it can indeed be line bred.
You could just start out with your single male and a normal female and take it from there..

Cheers,
Sandor

Hi, The Black and what I call "Bull Nose" BN"s. those are (almost certainly) not genetic modifications. I believe the more common term for that in English is snub nose and it is most widely believed to be the result of some kind of deficiency early on in the raising process. It is kind of uncommon ...

Hi Ron, this looks to me like an "off-coloured" male of your common Ancistrus. There is a solid black strain of the common Ancistrus in Germany, but it is not very popular (and it is "more black" than your fish, as it does not show the spots visible in your pictures anymore). See here . There even ...

Hi,

there is a Lamontichthys in the second picture..

Cheers,
Sandor
