Why The Most Expensive & Rare Plecos Still Have No Scientific Name. The History of L# Naming System

How the L Number Plecos got their names, and the history of Datz Magazine in Germany. Why we use L# or LDA# For naming new plecos in the hobby. When did the system start, who started it, and why is it better than common trade names from the aquarium hobby while we wait for a latin name to arise from acedemia and ichthyologists.

I used to really dislike the L number system, now I wish it was the only system 😆 thanks for sharing 😊

[@youraveragefishkeeper]

This is my kind of talk 😏

[@Fishtory]

Average? Jk thanks haha

[@Peterisbilt]

That blue phantom pleco is gorgeous

[@freya7084]

I love plecos. I had a common female when I was 7 that died when I was 19. I cried :(

[@tthappyrock368]

Never knew there were so many types of plecos!

[@bevfrigon7142]

Wow, so many! I've never seen any of these except on some videos. Very beautiful colors and very interesting!! Really enjoyed this, thanks Alex❤🇨🇦

[@alishanas9380]

8:17 - L075 Peckoltia sabaji aka para pleco. Named after Dr. Mark Henry Sabaj Perez, interim Curator of Ichthyology at the Academy of Natural Sciences of Drexel University. He is speaking at the Bucks County Aquarium Society in October. Topic is his recent trip to West Africa.

[@Fishtory]

Awesome info, thank you!

[@Finkeldinken]

Oh, I FINALLY got around to this one! Loricariidae are some of my favourites, so I knew the info, but oooh, they are so pretty! Back around 15 years ago we had a L breeding WIZARD named Paw here in Denmark. I wonder if he is still active in the hobby. Super sweet guy too. I believe he was the first to make L046 around here.

[@Fishtory]

Glad you enjoyed it! Ill check out this Paw fella too! Thanks

[@yehoshuacirt8645]

I bought an L81 golden nugget here in Israel September 12 2001. And I still have it. The yellow on the tail and dorsal fin has mostly disappeared. Other than that, there is no tangible sign of age. He's 5 inches long.

[@Fishtory]

Whoa! Thats awesome. You are an amazing fishkeeper my friend!

[@TedH71]

Have you thought about breeding him just in case?

[@yehoshuacirt8645]

@@TedH71 I have only seen one L81 and that I purchased. So I couldn't breed them if I wanted to. But I never did want to: some time after I got him, I changed out the gravel for coarse black sand that I've had for years! I didn't get the connection but the Baryancistrus became dull and dark and as said the yellow disappeared with age. So of course the novelty was no longer there and add to that the tedious daily feeding of cucumbers for years and you can understand why the love wasn't there anymore. He was barely any prettier than a common plecostamus. I thought that's the way it goes with an old fish. Who'd want to breed them? Three years ago I went white with the gravel. And the fish lit up its dull brown became a richer lighter brown and the whiteness of spots popped as of circa 2001. It's amazing what a substrate color can do for a fish that comouflages. But as said I have no access to small spot golden nuggets. So I can't breed them. Which is a shame as it proves in essence to be a pretty pleco.

[@ab4877]

I am also seeing a "C" system occasionally used with cories. Considering how fast they are also being introduced (and the nearly 200-and-growing-number of Apistogrammas) it makes sense.

[@Fishtory]

Yes indeed and a sw system for loaches

[@Constantine_Cvl8]

They also have "ER" for unidentified Erromyzon loaches

[@valeriee9532]

Great video. I didn’t realize how many different kinds and colors of plecos exist. They are so beautiful! I have one albino pleco that I’ve had three summers now. During the warm months it lives in my 500 gallon garden pond just outside my dining room window. I bring it indoors to stay in an aquarium (that I have just for it) once it starts getting colder. It’s such a nice fish!!!

[@Fishtory]

Awesome!

[@AquaJoyClub]

What a well-timed video. I was wondering about this naming system! Thank you for making this video :)

[@Fishtory]

Sure thing!

[@angiebear8727]

Really interesting. So many plecos so little naming 😊

[@emberframe6994]

We get some crazy looking plecos, there are also some caniverous plecos.

[@Fishtory]

Ahh yes! Good point. I cant believe i skipped over that lol. Thank you

[@Chompchompyerded]

Zed is the word for what in America you call a "Z". Naught is what people in the US call zero. Canadians also tend to use "zed" and "naught" but don't always. It somewhat depends on what part of Canada they're from. In all other parts of the English speaking world it's "zed" and "naught" for "z" and "0" respectively. That blue one with white spots on it is gorgeous! I've been wondering for a long time what the L numbers were all about. I wondered if they might refer to cross breeding, but when I saw that certain plecos with L numbers in front of them were captive bred, I sank back into the dispair of thinking I might never know. Now you have sorted me all out, as you have done on so many other issues having to do with fish. I'm so glad you're out there and that you know so much about fish, and further, that you are willing to share in very well produced videos. Big thanks go out to you again!

[@MandyJane123700]

This is really interesting, and I loved seeing the images of different plecos.

[@michellebarnhill5130]

Looking forward to hearing about this... I had wondered about all the L going on

[@edwardwiddup]

Nice to hear some proper science for once. Thank you. It makes you wonder how many other species on the hobby are in fact undescribed by science.

[@Fishtory]

Many if you count hybrids too!

[@Rorther]

I would love a video like a timelapse, from an aquarium to start to like 1 year or so. I really watched many of your videos, but sometimes i don't know how often i should add nutrients (food), or trim de plants, water changes, or adjust any parameters. That would give us a better notion how it all works. Thanks for your very informative videos, as always

I used to have a panaque with unclear L-number. It's favourite food is driftwood. Small guy but it regularly choked up my high capacity canister filter. Crazy guy.

The only "pleco" I want right now is the blue eyed lemon ancistrus (sometimes called L144 but its not actually the true L144). Well that or the bulldog pleco (chaetostoma). Neither of which I can find in stores. Tons of zebra plecos and golden nuggets though.

I've always wondered which Pleco L001 is - do you know?

[@stephenlyon1358]

Hey guys, hopefully sometone can help with this. I have a shrimp colony tank that ive had for a few years and its doing very well - but I picked up a bunch of ramshorn snails too that are not doing well. They seem to be dying when they are the size of a pinky finger nail, the first snail I saw grew around 4 or 5 times the size of this. I added a bunch of dead coral into the tank but it had no effect, a shopkeeper told me it was the wrong type of calcium so i bought some "mineral blocks" to add to the tank. The issue is that it says its for reptiles and im wondering if it will harm my shrimps/snails?

[@Finkeldinken]

You should be fine. Do you know anything about your water parameters in general?

@@Finkeldinken its hard now because i put corals in. Everything else fine, it's planted tank for about 18 months. About 30% of the tank is java moss.
