Want to confirm ID of two Pseudacanthicus

Hey all,

I just wanted to confirm the ID of these two fish:

Number one was sold as L114, but I doubt it is (looks more like "L600" to me).

Taken yesterday, with flash

Taken about a month ago, without flash (and in different tank)

Mouth up close and personal

On a side note: (at least imo.) there are a rather distinct differences between the two, but which one of the two is supposed to be the true Pseudacanthicus leopardus, and which one is Pseudacanthicus cf. leopardus?
It's quite confusing, as some sources (like PlanetCatfish) say L114 is it, others (like Mergus Wels Atlas vol. 2 and the Datz L-Number Special) point towards "L600"-like fish.

And the second one (my guess is L097):

Taken yesterday, with flash

Taken some two weeks ago, with flash

Mouth shot

Thanks in advance!

btw: I have 8 megapixel originals of these pictures, so if there's interest for any of these pictures for the Cat-eLog (I haven't seen any mouth shots, for example) just send me a pm or email (jonashansel at gmail dot com), and I'll gladly contribute them.

I have seen a lot of L114 and they are usual more orange then red, I have never seen any L600 so I cant tell you for sure what you have. Your second fish is .

Hi Janne
for shure Pseudacanticus leopardus.
L114 = mor ,biger Spots on the Head
Pseudacanticus leopardus = no spots

why you cal the Pseudocanticus leopardus => L600 ?
L600 not oficial Number !?

As far as I am aware, the "real" P. leopardus from the Rupununi river in Guyana has much thicker and more vivid red/orange bands on the tail/dorsal. The body pattern also changes on the head to less spots.

The P. cf. leopardus (L114) is from the Rio Demini (Rio Negro drainage).

They may or may not be the same sp.

Your fish looks like the "real" P. leopardus.

I don't know where this L600 business came from as L numbers have only just reached L400. It would be madness to complicate the system further by having a non chronological sequence.

L-600, as far as I am aware, originated in SE Asia to label, the above identified, "true" P. leopardus and is not a DATZ L-number. For most people, L-114, the Rio Demini fish, is P. leopardus, thus L-114 couldn't be used for the "true" P. leopardus and a new marketing name was established.

I'm aware that "L600" is not an officially recognized number, but (unfortunately) it has found its way to hobbyists and dealers alike: on the plus-side, it makes it easier to distinguish it from L114 without having to resort to throwing around scientific names (especially since with these two species opinions still seem to vary as far as who is who is concerned).

So for the time being, it is as followed?
- L114 = Demini Leopard Cactus Pleco = Pseudacanthicus sp.
- "L600" = Leopard Cactus Pleco = Pseudacanthicus leopardus

Thanks a lot for your input, btw!

Looking at your small photos...the L190 is actually a young L330 Panaque sp.

Really? I've wondered about that before, as his lines slowly began to break about a year after I bought him, but didn't really pay much attention to it (as far as care and feeding are concerned, it doesn't make a difference anyways...)
I've tried to figure it out before, but never fully understood what to look for when comparing young L190 and L330...
