I see them every once in a while, last time was a three incher at Wal-mart in a tank full of mixed catfish labelled "assorted catfish $6.99 each".turtall said:I've used it before and, as advertised, it cycled overnight. Good point.
BTW, I've never seen a callichthys catfish in any fish store. In fact, the only one I ever saw went under the name 'Puff Daddy'.
I have read the literature on the biospira and while I haven't used it they have a good reputation, just make sure the lfs stores it refridgerated, the local Petsmart has it on a shelf, the dummies.
