I love these guys and currently have a single pair that I picked up at my favorite LFS
. You may already know this, but in case you don't:
L134 are listed as "omnivorous", but skew much more heavily to the carnivorous end of the spectrum. Wafers don't excite them much, nor will they play the standard pleco role of clearing out your algae. That being said, I still feel that they are a great addition (given appropriate tank conditions). Their smaller size and at maturity and relatively peaceful nature makes them an option for more aquarists.
I am actively on the lookout for another pair to add to a different tank, but have only seen them for sale online in groups of six or more.
PS-For those of you comparing prices, my local (Austin, TX) LFS
had them priced at $65, but offers an annual membership for $25. It gives me 15% off freshwater purchases, knocking these guys down to $55.25 + tax.
The fact that the membership paid for itself the day I bought it should clue you in to the fragility of my sanity.
