So, you finally bought that bright new aquarium calculator glass box. Youre standing in the middle of a pet store. The neon lights are humming. Youre staring at a assistant professor of bright blue tetras. Then, you look a chubby goldfish. Your brain starts acquit yourself the math. Youve heard the golden rule. You know the one. The famous one inch of fish per gallon rule. It sounds as a result simple. It sounds later science. But lets be real for a second. Is it actually true? Or is it just something we say beginners for that reason they dont perspective their animated rooms into a literal fish graveyard?

Ive been keeping fish for fifteen years. Ive had everything from a tiny 2-gallon shrimp bowl to a loud 300-gallon predator tank that took going on half my basement. Ive made all error in the book. Trust me. I once thought I could fit three Oscars in a fifty-five-gallon tank because they were "only a few inches long" at the store. That was a disaster. It was the great Ammonia Spike of 2012. I can nevertheless smell it if I close my eyes. My honest review of the one inch of fish per gallon rule? Its a filthy lie. Well, maybe not a lie. More in the manner of a definitely risky oversimplification.

Lets break all along why this regard as being is mostly garbage. Imagine you have a ten-gallon tank. According to the rule, you can have ten inches of fish. Cool.
