I was at my local PetSmart the other day just browsing and wishing. There was a middle aged woman there who told an employee she was setting up her 5 gallon tank after awhile of it being inactive and asked what she needed. She gets a gravel vac, a heater, a filter, and a couple other things. as she's getting ready to go check out, I hear her say, "I'll be back in a little while to pick out some friends for my Pleco". The employee just said okay. I was tempted to say something but would have probably been told to mind my own business so that's what I did. It makes you wonder what she's keeping that Pleco in now.
