So you think you own L-144, think again.

On and off for a while I have been following the story on L-144s as it unfolded over on planetcatfish.com. I know how confusing the world of L numbers can be, especially the identification part. Well it seems as if the opinion over there has settled out and here is the current info posted on the L-144 Data Sheet.

Under General Remarks:
L144 is rare. The fish sold as L144 is a different form, most likely based on Ancistrus cf. cirrhosus. This form resembling L144 can be found under as Ancistrus sp(4). The offspring of the only known import of this fish was line-bred to "fix" the colour form. All true L144 specimens are offspring from this single male.

Under Distribution:
A single male fish was imported from Paraguay.

I was thinking of getting a small Pleco for my 100 gallon, and I think what is confusing me is the different names given to Plecos that stay relatively small (4 to 6 inches).

I guess a better question would be if I do decide to get a Pleco, am I safe in getting something that says L144 or Bristle Nose? This way I know I'm getting the smaller variety.
 
and I just bought some calico and brown bristlenose, are you telling me they are impostors?
 
Aside from the lack of scientific analysis on the matter, the so-called L-144 are considerably slower-growing than Ancistrus cf. cirrhosus sp(3), which makes me doubtful that they're simply another selectively bred color variant.
Does anyone know the origin of the long-finned variety of L-144, or is that as mysterious as the origin of the more common BN as well?
 
It's never been a secret that they are rare and that they originated from one wild caught male in Paraguay, linebred to fix the color.
