Sad week : All my new fish died.
I had several new fish in QT.
One died the very first day.
The others were doing great for about 3 weeks. Eating, happy, no signs of disease.
Then suddenly over 3 days, all died.
Not sure what happened. No obvious signs of Ich.
I noticed some had red blotches on the side of a couple. Possible suspect is an Ammonia spike,
but really unlikely for my QT system, and test (after they died) showed zero.
Perhaps some other disease. Strange that they would go 3 weeks and then all die at once, but
perhaps that first one that died did it.
It is in the garage, which was pretty hot this week. But temp is ok now.
For reference: I have a 40G QT tank, air-stone, heater, foam filter, and powerhead.
PLUS it has a salt water exchange system, of about 5 gallons per day.
Major bummer.
