My local Petsmart is sometimes hit and miss for fish.
For the most part, the staff that does the fish usually does not know jack squat. Fortunatly, the kinds of fish the petsmart sells I know more than enough.
Dry fish goods are good, and other pet supplies are just fine too. But as for the fish themselves.........................................
I would say they are at, about 80%, in fishkeeping. I do sometimes see dead mollies and other tetra's and such, smaller, easy to find fish. I will say something and it is taken care of. Each time I've seen dead fish, you can tell they have not been dead very long. But it still happens, dead fish that is.
As for thier 'meaner' fish, like the oscars, dempsey's and such, I dont like how they feed tehm only once a day. You can tell that the 'carnivore' fish are not maintained as they should be. But I can understand that PS is not in the bussiness of raising fish, only 'holding them' until the sale. But still, a tnak with 3 oscars needs more than a small cup of pellets. They dont feed live fish to them at my PS, and as you know, small oscars and such are quite the hungry little fish as they are growing up.
