Went to petsmart for some feeders. They were out, so I asked for 10 of the cheap zebra danios. I was told in a rude manner that she could not sell them to me. They were pets. So I said, "so it's ok with you if my pet starves to death? She informed me it "wasn't nice" to feed fish to other fish. Has anyone had a similar experience? Never going there again, by the way.
