, and there are several species are generally the smallest that are commonly available. Paraotocinclus
are generally a bit larger, but still quite small.
Other small Loricariads include several Peckoltias
(Candy, Clown), Rubberlip (Chaetostoma sp
), and one that I bought labeled 'Bulldog' that is absolutely NOT a Rubbernose or Rubberlip. The genus Rineloricaria
has generally finer bodied fish that have therefor a smaller bioload than most of the Loricariads. The Farlowellas
are also very thin, so while they may be 6"+ in length they also have a smaller impact on the tank than their plumper relatives.
You can search at planet catfish for small cats. Go to one of the species that you know is small (Otos, for example) and look for a search feature that says something like 'Find fish the same size'. The search is not just among Loricariads, but is within the Catfish family. You could start the search from an even smaller fish (Cory hastatus
or similar) and see if any Loricarids show up. http://www.planetcatfish.com/catelog...hp?family_id=4
