1 inch per gallon is an old standard that gets repeated a lot and is a good starting point and works well for most small fish but for fish 3 inch and above or odd shapes it does not work as well http://www.aqadvisor.com/. Is good but i would not go over anything 75-80% it estimates are biased on never over feeding or missing a water change
Yup. Works most times for smaller fish like barbs, tetras, etc. but if u go into the semi-aggressive/full aggressive, then that method doesn't work. Especially with the fish that grow longer than a foot.
Example: a 12" Pleco would definitely not be happy in a 15 gallon tank. lol
