All my local PetSmart stores have reduced the size of their fish selection and streamlined the dry goods as well. I know one of the dept managers and he said the reduction in tanks was due to parts availability for their previous filtration systems and that they changed over to smaller central units.
My local Petco have fresh and salt, but crappy selection. I just check their tanks for anything interesting that's mislabeled that slipped in on their regular shipments.
Electric Blue Acaras around here are only bringing around $20 at the LFS's I frequent.
