Fish died

[maybe]

So I just came home from vacation for 3 days. Before I left I feed slightly more than usual. Then when I came home I found my domino damsel and maroon clown fish dead. Here are the water parameters.
pH is 8.4
Ammonia is 0 ppm
Nitrite is 0 ppm
Nitrate is about 5.0 ppm
and Salinity is 1.025

Sorry to hear about your fish. How long has the tank been setup? How long have fish been in tank? Those hydrometers arnt very accurate.

 

[maybe]

The tank is fully cycled and it was running for more than two months.

Now that is just the most mysterious thing ! Nothing wrong with your water; no way the fish could have starved that much in three days.....

Ammonia spike from the extra feed?
Tank is young.

 

[maybe]

No that picture was when I just came home.

No that picture was when I just came home.

a spike within 12 hours of extra feed would likely show 0 Anmonia 2 days later.

Power outage maybe

Any chance the AC was too high/low during your vacation and cause tank to over heat/cool?

Hard to tell if just decomposition but both fish look like they have tail and fin damage / rot

 

[maybe]

Now another one looks like it will die. It looks weak.
