Jan,

If the fish are fed sparingly, or left to fend for themselves, I think that
at least 5 or 6, and maybe as many as a dozen (unfed) could be more than
happy with that much water. You will probably go through the cycle, just as
if you had a separate filter, but the bacteria will grow on any surface.

RTB,

What's your best guessimate for a filterless lily pond ~ 900-1,000 gallons
w/spitter, in regards to how many fantails in the 3-4 inch size one could
put in there without problems? I'm hoping 5 or 6. What do you think, is
that stretching it? ~ jan

If you keep the number of fish down, you probably won't need any filter.
The sides of the pond, the plant roots, and pot sides will develop into
filter area. I would run an air stone, just to keep the bottom water
mixed
with the top water, and keep it from going stagnant. Keep measuring
ammonia
and nitrItes, and after the pond has a chance to cycle, if you are
getting
either, then it would be appropriate to get some other filter on the
system.
