A few months ago, I got a fish. Then a few more. Then a few more. Now I'm gonna buy a 30+ gallon tank and decorate it to the max. I even have a 2.5 gallon with a Crowntail Betta in it in my room! I think Cory Catfish are adorable, and it's the same with Bettas. I can sit and watch them for hours on end, too! Is this normal?
