I just want to confirm the IDs on these 2 types, which were bought seperately as L66s.

Type A. These are are real dark smokey gray in color.

Type B. This guy has a yellow tint to him, but not as yellow as my L333s. I thought perhaps a B+W L333?


These two types look too different to be the same L number in my opinion.
Thanx.

I edited your post to show the pictures directly rather than a link to them.

I'd say the first one is certainly L066 - it's got the blunt head as well as the right pattern.

The second one, I can't really say.

Yes, they are both L66 and the second one is oldest.

The Type A group just started breeding so I wanted to make sure I had a positive ID. So Janne, are you saying this group will change color as they get older and start to match the Type B fish?

Thanx again.

not necessarily.. , can be a number of reason, why the color is different.. pickup location from the wild... age does play a role as for type b, may be a nicely aged adult ,also has type b settled in good shown its true colors, and not stress colors?

Type B looks like a L401 to me.

Yes the colour can vary a little depending on several things but both are still L66.

This is a typical L401.


Janne

Looks like this, though depends on the size I guess.

Yes L401 change also with size like you showed on the last picture, but "Plecoboy's" pictures shows both L66.

Janne

Any chance of a clearer pic of the type B fish? I don't want to disagree till I'm sure, but something about the caudal shape doesn't look right for L66.

Janne, why do you say that second fish is L066? Clearly many of us don't think it looks like a "typical" L066, and I'm wondering what your experience has told you so we can better learn how to id these fish as well.

Alright this is the best picture I have for right now. I need new batteries for my camera.

Type B is what we first knew as L66 "original L-number", with age they get very stubby and greyish in colouration and they are the most widespread species in Rio xingu from the influence of Rio iriri down to Belo Monte, they also occur in the small tributaries to Rio xingu along this part of the river.

Janne

Thanks for the info!

So basically I have 2 variants and should keep them separated?

They are the same species, they may come from different localities but the huge different is the age of these 2 specimens.

Janne

So are you saying the Type B fish will lose his coloration and turn into the darker gray fish represented by Type A? Before you said you thought Type B was the older fish. I'm not trying to be a pest, just making sure I understand this.

Thanx again

I thought "Tybe B" represents the older one too!

Have I really said that? I said that "type" B is the oldest one and it's very stubby and greyish in the colouration.

Yes, they are both L66 and the second one is oldest.

Type A is a much younger specimen with a dens pattern, when this one will be as old like type B it will also be very stubby but much darker and greyish.

Even very nice patterned L66 change their nice pattern to be much less nice when they get old and stubby like type B.

Am I more clear now? ;)

Janne

I think the problem is my pictures of Type B aren't really good. When I shine my flashlight into the tank at this fish he has a fair amount of yellow coloration in him, unlike my Type A breeder specimens which are the gray ones. I'll post some more pics soon.

Thanks again.

When you use a common flashlight with yellow/red colour spectra you mean ;) in normal daylight is she yellow too?
I wrote she because of these pictures it looks like a she and not a he.
Yellow like this one? Janne

Hi,

i send also some photos my L 401. Some fisch have gray stripes (mostly female) and some fisch have more orange yelow stripes (male),
and base have blueish tint.

and female

and more photos

and one special in a houndreds juvenily with board stripes )

Yes Janne, he is yellowish like the pic you provided. If I shine the flashlight on the Type A fish, they stay gray. Nice pics Claro, but my fish doesn't match yours.

plecoboy,
Yeh, what to say... L66 with very large variation ;) To be honest, I think it's not possible to refer many of these different looking Hypancistrus from the lower xingu to a certain species, it's to complex. Thats why I also call the species in the Cat-eLog H. sp "Lower xingu" for just that and nothing else, there are to much differencies to be only 1 species involved.

Janne

Ok, here are a couple more shots. It was a bit stressed as I kicked him out of his cave. Thanx again, Janne.
