Hypancistrus sp. L173?

Hello!
The PC cat-e-log indicates that L46 and L173 are the same.
So...if you had a fish like the L173 pictured in the new hard cover "All L-Numbers" (but more tan or flesh colored than white), what would it be?
My fish was collected in the same locale as the L174; in the Rio Xingu near Altimira, Brazil. The pattern is quite variable between fishes, including the head and nose (and does not resemble the disctinctive L46 nose pattern of alternating white and black vertical lines)

Hi!

If you look at DATZ, L173 is a color morph of Hypancistrus zebra

What size has your fish?
Any thing special except the colour to make u^you and us believe it might be another species...

Cheers

Yann,
Thanks for the response. My suspiscions that it might be another species are based entirely on the apparent visual differences in colors and patterns. It does, however, have the same body size and shape of the L46, but as I do not know how old these fish are, I am unaware of how large they WILL get.

PICS ARE NOW INCLUDED WITH THE ORIGINAL POST.

Pics have been added to the first post of this thread.
See what you think. Is this L46?

333 is my guess

Hmmmm. L333?
If it is, then every fish was/is juvenile. There was nothing in that whole box of 20 individuals over 3". That seems unlikely, doesn't it? and IF (which I can not verify at the moment)of these 3" or less fish are showing definative odontodal growth, then they must be adult and can NOT be L333. Right?

That is my opinion.
I am often wrong.

Kevin,
according to DATZ L-046=L-173. L-098 is the scribble lined zebra.

I have found many vendors trying to market fish under the wrong name to make a sale.

IMHO - try to get a picture of the actual fish before you order.

I don't think it is L-173 at all but I am no expert by any streach

Hi!

According to a contact of mine L173 is a regular in L46 spawns. So if you just spawn enough L46 youll receive a L173 from time to time...and if you spawn L173 youll sometimes receive normal L46 offspring.

Hello,

Will give it a L236 :?:

probably a stupid question but anyway...
If you get "L173" from L46, then why are we still talking "L173"???
:?

Kevin,
Can you take some new pictures? I dont think they are L173 or the same species as H.zebra.
I have not a really good picture to compare with but look at the head and the caudal fin in L46...they are a little special to this species.

Maybe your belongs to what we have discussed before L236/L287 (and if I am wrong in that topic yours should be L287) This

Well...here's another picture to stir things up. It comes from page 133 of the new hardcover Aqualog "All L-Numbers".
I have circled the area of the pectoral fin in each picture for comparison.
Does this show (prove?) that the multiple photos of L173 in the book are not all the same species...and that the left image is Hypancistrus zebra while the right image is something else altogether (possibly L236 or L287 as Janne and Pandadosmares suggest)?

All of the fish I purchased as L173 (the corpse pics at the beginning of this thread) have the alternating black and white pattern at the leading edge of the pectoral fin ray NO MATTER WHAT THEIR INDIVIDUAL BODY PATTERN. As a matter of fact, all of my L174 do too and these fish are said to co-exist in the same locale of the Rio Xingu. NONE of my Hypancistrus zebra have this pattern. Their pectoral fin rays all look like those in the lefthand picture=white.


Y'know...maybe all of you already knew all this and I'm the last to catch the train.
If so...my sincere apologies for taking up all this space and time.

Another difference between the two pictures is that the barring on the paired fins is oriented differently. Note that on the H. zebra the pectoral fin bars run parallel to the spiny ray, but on the other picture the bars are perpendicular to it (and are extended onto teh spiny ray as Kevin pointed out). The bar orientation on ventral fisn is also different.

Is there is different number of rays in the dorsal fins as well? I count six clearly in the H. zebra... but there looks to be more in the other picture.

I was at the lFS yesterday they had 4 or 5, L 333. All at about 3 inchs. Two or 3 of them had odontodal growth at the gills. The odontodal growth was small but it was present.My L 333 is about 3.5 or 4 inchs but has no odontodal. its behaver sugest that its a female from all ive read. But the first pics you posted did look like young L333 to me to. But some of the markings dont fit the L 333, but im no expert eather :roll:

My first reaction to the aqualog and L173 was that most of the pictures dont look as L46...color of the eyes...the caudal fin with equal lenght of the upper hard ray as the lower and striped pectoral fin but if you instead compare them with L236 or L287 they seams to be identical...all have brown eyes...same pattern on the pectoral fin and same caudal fin, the only different between L236 and L287 is the body color with L236 more white and L287 more tanned but that depends on the invironment...I have several Hypancistrus species that change between this ground color so it's not unique. I think L236 and L287 are more related to L174 then to L46 and maybe they are a natural hybrid between these two or several??? Just a thought...and no science :wink:

The last picture shows a young L66 in the background.
