I was at PetSmart about a week ago and I was exclaiming about all the fish they had and how well taken care if they were (they really were. Their tanks were cleaner than the ones at my LFS
) and a man comes up to me and says "I'm sorry, I don't mean to eavesdrop but do you know a lot about fish?"
I tell him I love fish keeping and know a bit.
"Ok well, I bought my daughter 10 fish to out in her 10g tank. When I woke up this morning 9 of them had disappeared! I think one of them ate all the rest!"
I then proceed to ask what kinds of fish he had bought her.
Turns out he had bought one Oscar, and 9 neon tetras.
The worst part: "The lady that was here said they would get along fine!"
I had to convince him that an Oscar needs a mug larger tank then a 10g and they only really go with oscars.
