Some myths ,like many facts can have an exception.
The inch per gallon is pretty good if you are keeping neons,or cardinals.
10 neons in 10g,not best,not worst IMO
10" Oscar in a 10g?
Lets discuss why the myth exist,or the misunderstanding behind them?
I have wondered where this came from. I think aqadvisor or some other site gives a bit of detail of the history which I found fascinating.
I get it to work in my DT however it is modified. I couldn't even really explain how I modify it because as pointed out above, there's body shape, etc, etc to consider. One that I did like about it was that it was (most of the time) including finage but importantly was adult size. I have dim recollection of that being explained to me that 'yes, fish do really grow and thus, no more goldfish for you (unless we can interest you in a second tank)'.
Here in Australia I rarely see this rule or guideline pop up now (maybe the metric conversion doesn't work so well
). I've never read it within an aquarium book for some time.
However misinformation on way to high goldfish stocking rates by something like every 5 gallons is still out there. Actually come to think of it - most books I have read, skip stocking rates completely (will have to double-check that).
