So I used to have fish who lived in a fish bowl and my mom really hated it. Me and my sister had a bowl-cleaning thing worked out where i would clean it, then she would clean it the next time, and so on. Problem was, she sometimes wouldn't fulfill her side of the agreement and so sometimes the bowl stunk. Because it didn't have any kind of lid or anything, water would occasionally splash out of the bowl. Well, now I really want to get a little fish tank, like the tiny ones that only hold like a few tetra. My friend had one once and it was always nice and clean and didn't stink and never splashed out because tanks have lids etc. I told my mom about these pros and she still wouldn't listen. She just said, "I really really REALLY don't like fish." So I need some good things about fish tanks that bowls don't have, so i can convince my mom to let me get another fish. Thanks so much
