So I'm curious, I keep seeing those coffee tables that double as a fish tank (or is it the other way around?) and what is everyone's opinion on it? Aesthetically they're kind of fun to look at, at least while they're newly set up, but then what about poop, algae, etc.? Not to mention the fact that you're looking at the top of fish when it's usually the side that's pretty. I'd never get one because my coffee table doubles as a collector.
