Damn i would have bought them for that much. Killergar, there are many plecs sold in place of the hypancistrus sp. zebra (L046), and it would be unusual for them to be priced so unbelievably low. Most "zebras" are other different Hypancistrus species, and even some Peckoltia.
I wouldn't say they are particularly boring fish, the genus as a whole in my opinion/experience are quite personable, but i know they are one of the less active Hypancistrus species.
