ok if ammonia is killing your fish take stock
only clean filter sponges with water drawn from the aquarium
if you have a heater put it in
turn the temp up to 28 deg C
increase surface agitation to improve oxygenation by optimizing filter
output
remove carbon or charcoal from filter
use correct dose
water change in 3 days and repeat
don't water change more than 50% if you are not going to heat and pH match
replacement water before adding it

Ace, thank you SO much for the advice. Put a heater in and all of a sudden
the little guy's doing barrel rolls and looks happier than ever. Most of the
white spot has disappeared now too, so I'll keep treating him for another
few days then think about restocking the aquarium.

Thing is - what am I going to do with him? If the aquarium won't take him
back, I don't know what to do... don't like the idea of having to throw the
critter in the pond, but as you said in the long run this is not the
aquarium for him. I assume that he can co-exist peacefully with tetras while
he's still so small? (he's about 2 inches)... that said, I don't really want
a messy fish like that poisoning the water for all the others....
