Hi everyone

I have this issue on my hands where i have already gave up on searching
for an answer.

It all began with addition of neons and goldfish to an aquarium where i
have already had two eels and two arowanas.

Anyway two neons and goldfish died in about two week period where i
noticed that they had hard time coming up to the top to feed, and when
they tried it seemed like they needed a lot of effort to swim up.
Eventually i have

You caused your tank to cycle, if it ever did at all. Goldfish crap heaps
and produce copious amounts of ammonia. If your filter isn't up to it and
you state you don't maintain your tank other than topping up an absurd
amount of evaporated top water then I'm not surprised you have had
everything go to that big tank in the sky.

Poor fish - all of them.

If I were you I'd sort out the heat problem, sort out your biological
filter, do some research into community/tropical/cold water species and stop
being cruel through your apparent ignorance.

Have a great 2005, a better one for any future aquarians you take care of
and may the great Lords Avalokiteshvara and Mayatreya bless you and your
aquarium. May you be enlightened to the realisation that you are playing
with the fate of other sentient beings.
