Hi i just bot this plecos i bot them as L-201 But i Dont think they are.
i dont thing they are L028 all so i all redy have L028.

I am raising some I bought at about 3/4 to 1 inch which are now about 2-1/2 inches. Mine look like the photos in the Cat-eLog.Very dark field with fewr but larger spots of an off white and yellow tinge to them. I'm pretty sure they were identified correctly but there are several similarly marked species. said not to be L201.

I guess all I am saying is that I would rule your plecos out as L201. I am not very familiar with the Hypancistrus spp from the Orinoco draingae aea and only have this one species.

have you look this?

the last in the photo i thing is the same with my hypancistrus

There are several Hypancistrus species that are darkgrey/brown/black with white/whitish spots.
Off the top of my head
(aka L005, L028, L073)








I'm not saying all of these are close to the fish you have, just trying to show that it's not just a case of looking at the fish and saying "It's X" - several of these fish are not at all easy to tell apart - especially as the L-numbers are essentially identified by a combination of capture location and photo - and I expect you don't know the capture location.

Jon Armbruster's site generally only show fishes that are scientifically described, which isn't all that we as aquarists may see in the shops.

AFAIK the fish in that picture does not have an L-number. It is from the Takutu River (according to the specimen jar) which I believe is not as well collected for the aquarium fish trade, although there are a few L-numbers from there (ie. L306). It is also rare (apparently); that fish pictured was the only one captured on that collecting trip. I guess we could call it Hypancistrus sp. Takutu or something.

Not sure if it is your fish. With only one specimen I can't really tell what the range of variation it could have.

Milton,

Thanks for the "insider" information. Yes, Guyana is definitely not a common capture area for fish in the trade - there may be L-number fishes from that area (I certainly remember entering Takutu to the distribution database), but they are probably collected from occasional private exports rather than common collection for the trade.

I don't know if we should get that fish into the Cat-eLog - just to show that it exists, or wait for it to be described...

Hi again
the fishes come from venezuela .they came together with hypancistrus contradens.

i have L-201 L-028 and contradens but they dont look the same at all

That would make it Rio Orinoco drainage, which if we assume the Cat-eLog has all Hypancistrus in it, makes it one of these.

Of course, I'm not 100% sure that ALL species [1] of Hypancistrus are in the Cat-eLog yet.

[1] I use the term species in a looser fashion of "entry in the Cat-eLog", rather than "scientifically described" species.

i was thinking Hypancistrus lunaorum but not sure thanks for the help

what bout the sex ? Ok the big one is a male,the ather two?

I would say the two smaller ones are too small to sex. Grow them up a bit, and we should be able to tell.

Hi,

..just to add my two cents:

AFAIK the fish in that picture does not have an L-number. It is from the Takutu River (according to the specimen jar) which I believe is not as well collected for the aquarium fish trade, although there are a few L-numbers from there (ie. L306). It is also rare (apparently); that fish pictured was the only one captured on that collecting trip. I guess we could call it Hypancistrus sp. Takutu or something.

Actually, Ingo Seidel, Andreas Tanke, Jens Gottwald and some others were in that area last(?) year and found a Hypancistrus species there (dark with whitish spots). Those that were in Hannover, might remember that from Ingo´s talk. I think, the picture is also in the conference book.
That species got an L-Number very recently, I just have to look it up (should be somewhere in the 430s). There´s a bunch of additional L-Numbers from that area now..

Cheers, Sandor

So My fishes maybe they are new species?

Hi.
Your catfish looks like one of mine L-339 in the cat-elog.
It's my fish on this pic http://www.planetcatfish.com/catelog/im ... e_id=11054

That would explain it, the only L-numbers I know are the one in the Cat-eLog.

Hi,

for sake of completeness:
it is Hypancistrus sp. "L 429" and was caught in Rio Jatapu, a tributary to Rio Uatuma.

Cheers, Sandor

i thought so, how long you have the fish?i sow you breed them

From Rio Takutu / Rio Tacutu we know of a Hypancistrus which is black with white spots; . That makes it very likely that this is the fish in the jar

Like this?

I saw a group of them for sale recently in my favourite fish shop

Indeed, I figured that would be what it was!

This looks like L136, which is far more common AFAIK... Not sure though.

It was sold as L404 by some people who had imported them and whose knowledge of plecos I would trust. But I/they may be wrong.
