So how do you judge how many fish is the maximum, so to speak, to put in the tank between a long and a tall tank? I know of the 'one inch of fish per one gallon' theory, but I'm guessing it isn't relevant, since the decision is between a long/tall tank?
I was thinking of getting a 30 gallon myself, and was deciding between long and tall. I see now that I was right in my logic of swimming space and gravel cleaning. I'm proud now
