A few months ago a young woman approached me with a 1 gallon betta tank and asked me how many "Nemos" she could put in it. I explained to her that she needs a much larger tank for saltwater fish. She said, "No, I don't want saltwater, I just want these Nemos." Again I patiently explained that CLOWNFISH are saltwater. **Blank stare*** Finally I just said, "They will die in there!" and left it at that. It's a good thing she's pretty because she won't get very far otherwise.
Today a man asked me what other fish he could put with his 6" oscar. I asked him what size tank he's got. 10 gallons. I told him he could put a bigger tank with it
