I often see requests for information on starting a very small 3 to 5 gallon aquarium.
Most people are asking about how to stock their 3 to 5 gallon tank — what can they put in it? Or more accurately, what can they get away with putting in it?
The most common (and undoubtedly excellent) advice out on the web is to put in a single male betta fish — and absolutely nothing else.
However, I believe that small tank owners not only deserve alternatives to the “betta only” model of very small aquarium keeping, but that there really are other good options available — if you’re willing to look outside the ordinary.
So what makes a “good” 3 to 5 gallon aquarium? You might not expect my answer. The things that make a “good” very small aquarium in the looks department are also important for aquarium health!
