Okay, first thing that went through my head was, glass... break... oh $h!t. Then, I was thinking, is anything going to try and eat the oscars? And then, can you imagine the feeding frenzy those things would go into? And you could probably never go swimming with them... Hmm, I'd get a shark (not the kind that would try to eat me either!)
What am I talking about, the only pool I ever had was blue and plastic and about six inches deep...
