Listless Goldfish

Bill, I seriously suggest you take the bigger fish and move him to
another tank.

I'd agree, except that the Nitrates are OK at the moment and all other
water conditions test fine. I suspect parasites were the original problem
due to

Ok and good luck. Its not a cycling problem. *Might* be an O2 level
problem which I don't think you can test for?

the timing with the new plant, although there are no visible signs or
flashing. I gave them some parasite food today, but they just spit it out
because they don't like the taste. They feel the same about their
medicated food. :-) Maybe I'll try soaking some peas in some
metronidazole, but I expect the same response. I might try a single dose
of Malachite Green to rule out parasites.

Ok, or the old penny trick.

Did you put that bigger filter in yet?

On my end, we delayed setting up our big 70G tank because we are using the
stand for the TV until our stuff arrives from Japan. Still debating what to
fill it with but the dimensions of the tank make it not quite right for
goldfish. Once they get to 10' or so, they have trouble turning around
grin. It's a relatively tall long tank for it's type. It would be fine
if I had a pond (move them outdoors when they get big) but I've no pond and
not really optimal weather zone for it (too cold, would freeze solid unless
I ran a heater and that would be very expensive).
