Hi!

I bought these two as a male and female L-066, though after looking at pictures in the CatElog I`m thinking they look a lot like the L-333. Could anyone help me determine what species they are and maybe gender as well?

Thanks!

These are exported as L66 but are not them, they share a lot with L333 but they have a different colour and maybe they are L401 which not yet have been official or aproved of Datz. They look to be a couple with the female on the first pic and the male in the next.

They look to be a couple with the female on the first pic and the male in the next.

I would say they could both be different species. The patterning on the head looks very different. More of a mottled/broken striped head in fish two, with more defined straight lines in fish one.

Fish one looks identical to my "L333".

Even in this species is the pattern extremely variabel and nothing we can use to separate species, I think there are a lot of work to do with this group of very similar species which are sold as L333 and lately even as L66. I recomend to only buy several species at the same occasion from the same shipment and not try to buy more later from an other shipment.

Hi!

I now know what they are, they are L66. I found some of the other people who bought fish from the same shipment, and they are positive that it`s the L66!

I`m glad that`s sorted!

Thank you for all your help anyway!

When you live in Norway and I think you have just recently bought these species, I also think I know from which wholesaler they come from. These are sold from the exporter as L66 but...that shipment and boxes was mixed with L66 and this species, they are very similar.
So some people that have bought them have for sure bought L66 but I dont agree yours are the same species.

Janne

They came from Imazo I am told. Was that what you were thinking?

Yes.

Janne

Janne: So what is your opinion about them? What do you think they are? Are they a new species?
I`m starting to wonder what to feed them. Will they eat the same as the other Hypancistrus?

Thank you for all your help!
Here are some new pictures, the one seen from the front is the one in the first picture in the thread.It`s a bit shy, so it`s difficult to get a good picture.

There are no different between this species and all other Hypancistrus species when it comes to care and feeding.

they share a lot with L333 but they have a different colour and maybe they are L401 which not yet have been official or aproved of Datz.

I have never seen any picture of L401 and I dont know either whom it was that first stated (gave this nb), all I can say that they show differenties in their body colour which are more yellow-brown then white or grey and their stripes/pattern is more darkbrown then black. It's not impossible they could be the same species that L66 for example but origin from another locality but they show enough differenties to be treated as their own species and should not be mixed before the science have done their work.

Hi!

Reminds me of these fish sold as L333 orange!!!

Janne: here are some pic of L401:Amazonas
L401 from Glaser

L401 from a L-welse.com member
L401 from another member of L-welse.com
same fish dorsal view

Cheers
Yann

In that case they are L401.

Yann,
Do you know whom that was that gave this species their new L-nb? I have heard that Datz not have accept L-401 yet...maybe I am wrong but it would not be fun with 2 L-401 in the soon future

Janne

Hi all!

It`s now been 9 months since I bought these fish, so now I am ready for a new evaluation on them.
I`m still looking to find out L-number and the sex of these two fish.
Here are some new pictures of them:

*bump*

Check out the pic of a "L236" from the website below. Looks somewhat similar to one of yours, but I really think you have a L401 and L333




http://rainforestpet.com

They are still the same species...both, If L401 are a valid L-no they are in that case L401 Hypancistrus sp.

Janne

For sexing pics from the top are the best.

Regards Michael

Right, I think I'll join the party on this one.

Here is my female "L333". She is approx 95mm TL.










The colour is a bit funny in the photos, she is a kind of creamy off-white with dark grey.


I was confident she was L333, as she seems close to the photos in DATZ/Aqualog.

This L333 from the cat-elog seems a very close match






But these two L401 also appear similar...






Any ideas?

How can you say the sex of a 9cm big L333? Normaly it is to smal for sexing.

The colour is no character for differentiate L66/L333. Only the form of the Body.

I have noticed that female Hypancistrus are usually about a third smaller than the male, so with the males at 150mm, a female at 100mm seems about the average adult size.

The fish in question has stopped growing, and has adopted the more mature, duller and less contrasting pattern coloration. She also displays the female body shape, and "classic" female behaviour, so I am pretty sure.

What has your experience been?

The colour is no character for differentiate L66/L333. Only the form of the Body.

Yes I agree, as color is often quite dependent upon lighting etc.

I can easily tell the difference between the L333 and L066/L236, as the body shape is much more elongated in L066/L236, with a larger caudal fin and narrower caudal peduncle by proportion.


However I struggle a bit more with differences between L333 and L401 (especially as I only have two photos of L401 to work with).

My opinion is you have a L400 Girl.

1. The small size. L399 is bigger. 5cm difference to a male is too much.
2. The clumsier Body

The most Photos of the L401 are no 401.

This must be a correct L401. Very different to yours .

looser, are you thinking that MY fish is L400?

If so, I'm not convinced.

I think the L400 has a narrower caudal peduncle, a less elongated caudal fin, and a more intricate/spotted pattern in the mature fish.

I think L401 is more similar, as the proportions and pattern seem to match.

Yes, this was my opinion to your fish. And I think BrilleGeit have an ordinary L66 like my. There is no difference to my small ones 7cm, BrilleGeit
is only a bit bigger:


Regards Michael

Sorry, here are some more pics of L401. The L401 has very big brown stripes. The fry looks like small L134.

http://www.l-welse.com/forum/showthread.php?t=14042

You can be sure this is no L134.

Regard Michael

Unfortunately I can't access any of the photos on l-welse.com

Does anyone have any photos of the Hypancistrus sp "Alenquer" to compare to?

I had a search through the forum, and most of the pics have vanished.
