[reef_dart21]

Naso all he did was swim around until he died from starvation (i think)
the pgmys they all do very good for about the 1st week then they all just quit eating anything.........although the fish i bought i never saw them eat at the lfs
the fish that died were

i think cream angel fish(ate)
naso my first tang (never ate except for some algea on the sand and never did anything but my six line would run into it alot the tang was 3")
thx for the help

Only things that come to mind:
1. stray voltage: lmbs/chromis less susceptible than tangs and angels
2. Fish are unhealthy to start with: Did they all come from the same place?
3. Ich...always have to consider with acute deaths
4. Stress (too many/too aggressive fish) combined with moderate nitrate levels
Personally I doubt that a nitrate of 20 or less could/would kill if everything else is OK. I also doubt it is a chemical toxicity as all the fish would be affected.

I would check for stray voltage.

the only thing i could think of that could cause stray voltage is my heater and power heads....how would i check if they are?

Take your shoes off and stick your finger in the tank....
just kidding, although that would tell you haha.
You can get a volt meter and put it in the water and see if it gets a reading of anything. If so then you have stray voltage. After this, keep the meter in the water and unplug one thing at a time and when the volt meter loses the signal, then you have found your culprit. Your lighting, pumps, powerheads, heater, protein skimmer, etc. could all possibly be the one doing it. You have to check everything until you figure it out.

thats how I found out a powerhead was bad. Barefoot, stuck my arm in the tank and bammmmm. I got the shock of my life.

 

[reef_dart21]

no shock because i wasnt wearing shoes

I have also gotten low level shocks. The only way I knew about it was a small cut on my finger. I add grounding probs to all my tanks.
