alright here is my opinion. I just recently bought 3 pbass. orino, mono and kelberi, non of which I want to take too many chances with, and I would definitely be pissed if I lost one.
anyways, non of the fish(esp. the kelberi) are easy to get onto non-live food. so I went to a lfs that had guppies since petsmart doesnt. and the fish got sick with ick. so fortunately they were able to convert to rosies although at first rosies were bigger then what they wanted but now are eating small goldfish. all from petsmart. and I have never had a problem with petsmart feeders now or in the past which includes many many feeders.
with that said, not all petsmarts are the same, some have employees that work really hard and know how to keep fish healthy and some dont. I suggest you get a feel for the petsmart near you and make a decision.
