I tell ya, watching the fish in a fish tank is surprisingly entertaining. And to anyone who has a fish tank I'd suggest getting snails too. As they're also entertaining to watch. Plus they'll clean the glass and decor for you. And if you're into gardening like I am, the aquascaping aspect is fun as well. Currently have Loaches and Tetras in my tank. Loaches are another really interesting sea creature to watch, as they have a lot of personality. Tetras not so much, but they look pretty.
