With off-the-chart ammonia, don't add *any* fish you want to live. The 5
fish couldn't produce enough to do that in a 55G tank. You must find
your source of ammonia before moving ahead.

If your water has chloramine, and you use one of the old hypo treatments
to remove the chlorine, that can cause exactly what you are seeing. Less
likely, but possible, is whatever is in your kitty litter. Most brands
are extremely *unsuited* to aquarium use. Test some by soaking in a
bucket of water and measuring for ammonia, without using any dechlor
product. Also check pH and any change in hardness before trusting it in
a tank.

If your tank is in SF, you probably have *no* chloramine (until about
2001, AFAIK), so check what else has gone into the tank.

The cycled filter is a good idea, but will not overcome chloramine
treated with hypo. The ammonia release is just too massive. Avoid, like
the plague, any product that claims to break the chlorine-ammonia bond
when treating for chloramine. At relatively modest pH (say 7.5 or a bit
above) 0.1 ppm of ammonium/ammonia will cause irreversible damage to
fish gills. My kits start with a minimum reading of 2.5 times that much!
At that level, the fish will never really recover, unless pH is below 7.

Very heavy planting can help a great deal. Just sticking in some val, a
few bunch plants, and a centerpiece won't do too much. You need *lots*
of plants and/or the invasive rapid growers like hygro, duckweed,
Salvinia, to handle that much ammonia.

That's the way it looks to me. YMMV.
