Ready to move beyond goldfish...

I like that profile site a lot too.
Good thinking about the likely fate of a returned comet.

I Think the best thing to do would be actively search for a pond, OR a Store that specializes in Pond fish and pond supplies etc.
IME the 29 gal, with Large weekly water changes would buy you the time for that.
I really don't know about the moor. 29 certainly better than 10, right? and Most likely better than returning it to the store...
You might ask the folks at the general coldwater or pond forum too.
 
Home Depot and Lowes have cheap preformed ponds. You can use a whisky barrel half that they sell at every garden center and put in a liner.
 
That's actually a pretty good idea, and I've been wanting a pond... but state laws require that a pond any deeper than 18" must be surrounded by a 6' fence, which is prohibited by the neighborhood's covenant. =/

Maybe I'll check that sort of setup tomorrow.

They do have 50gal half barrel preforms right? I don't fancy buying and attaching geotextile and and EDPM liner for such a small container.
 
Filteration is more important than tank size. HOWEVER, this does not mean I would put Oscars in a 140L tank. That said, my tank is overstocked but my water is always clear and stable. Filteration is more important than tank size, escpecially with species that do not grow quickly or are dwarf in size.
 
Opinion noted but I think you will find it difficult to find any expert that would agree with you. Filtration is by far the single most important feature of any tank and after 10 years of fish keeping and two books later I am affraid the science is also on my side :D
 
please don't read anything into a post, in no way did I call you stupid. I have no issue with your opinion however, there are times when experience and science simply do not lie. Its really as simple as that.
 
two sides of the same coin

Tank size and filtration are simply two sides of the same coin, which of course is Water Quality.

Water quality is the key, and it can be enhanced by filtration as well as total gallons allowed per fish. Tank size also brings in the consideration for swimming room and schooling companions.

So, back to the question at hand.... a pond for the goldfish may be a good answer, if summer and winter temperatures are reasonable for a small body of water. In addition to half barrels, you will find flexible instant ponds of the same size, and there are small livestock troughs that can be used also, similar to big galvanized wash buckets. You'll need electricity on a GFI circut to run a pump for a filter and aeration with a small fountain or bubbler. You'll need some shade, not too much direct sun if it gets hot where you are.
