just in case anyone else is looking for these, **************** has them for sale as "white spotted pleco" for $13.50ea. i've read some scary reviews of the company online but decided to ahead with an order and take my chances since i can't find them anywhere else, and most of the issues seemed to be during winter months.
shipping is a flat rate of $30 regardless of how many fish, but like most companies the shipping costs are non-refundable in the event of a doa. i decided to order 2 of them just in case there was a doa i would still have one, and wouldn't have to pay more shipping costs. if they both survive i shouldn't have any issues getting rid of one when they get older. i'll post pics when they get here.
