Three dead Balas floating. One Bala missing entirely!!

Oh dear

Surviving fish still seems quite normal. Dead fish, well it's hard to

Balas are quite sensitive, the others you are keeping aren't.

They could be the first indicator of a problem, like a dead
canary in a mine told the miners their air was bad...

ANY ideas? I've tested ammonia two ways and am now taking a sample of
what my tests say is pristine water to the lfs to see if their tests say
any different. Sure would love to know what happened and if it can be
prevented from happening again.

If your tests are coming back ok, it's hard to know. I've suffered this
(although none died they did get sick) and I do sympathise.

You say there is nothing poisonous etc. but are you home with the
tank all day? My own fish suffer every time they boil tar in the
road outside or the building site out back, you don't have to
cause a problem yourself for there to be one.

If I was you I would
a) do a large water change including gravel vac
b) add fresh carbon to the filter in case there are any poisons
c) oxygenate as much as possible (extra airstone etc)

and keep a close eye on them all :-(

Another thought - could there have been a temperature change?
Heat of the sun at midday, or quick power outage?
Or might the filter have stopped in a powerout, gone anaerobic,
and dumped toxins when it came back on?

You may never know the cause, but I wish you luck.
I know that it's very frustrating!
