I happen to be a very knowledgeable person on the L200. I have kept many over my years, as this happens to be my favorite pair of loricariidae species on the planet. L200 has two scientific names, one for the low fin variety, Hemiancistrus subviridis, and one for the hi fin variety, seen in my avatar, Baryancistrus demantoides. They are not rare, but have rarely been bred in aquaria. I have had a pair spawn, but lost the female and nearly lost the male to a filter failure. These guys get big, and actually vary a lot in color. There is still no solid proof that these two species, as well as L128, Hemiancistrus sp., are not all in fact one species just found in different locals. Planet catfish has a great article regarding the color range of the two L#'s. If you dig back in my started threads, you will see my old breeding project on these guys. Many pictures of the big guys, and gals.
