Or "one inch of fish per gallon". So that means if you had 10 neon tetras in a ten gallon tank that would be overstocked? and I guess that means you could also put a 10 inch Oscar in a ten gallon tank aswell lol.
Oh and my favorite is when I tell them a fish gets too big, the response is always, yeah but a fish only grows to its surroundings, so thatsok... I am like, oh that's right, they do only grow to the size of their tank, and then, they die....
