Thanks for the clear explanation for the cubic inch rule. Sure clear up a number of questions for me. Cheers.
guppy;1096410; said:This is something that comes up fairly often and is rather misunderstood therefore I will attempt to clarify the original meaning of the general guideline of "one inch of fish per gallon of water".
This is a suggested guideline for a well maintained and filtered tank.
It does not apply to all fish as some have differing requirements.
Here is the part that is being misunderstood.
The "rule" does NOT refer to the length of the fish!
The "rule" applies to the cubic inches of fish in the tank.
