I recently set up a 55G tank about 4 months ago, 2 weeks after I set up the tank i added 4 damsels and cycled them for the remaining time. Last weekend I went out and made my first big purchase of fish I bought a Porcupine puffer and a Trigger. Everything was fine they ate normal and the next morning the Puffer was dead. so i went back to my LFS and gave them a sample of my water which was.
pH-8.2
N02-0ppm
N03-0ppm
nh3/nh4-0ppm
Salinity 1.020
Temp-78
so after seeing that everything was fine they gave me another puffer. That puffer died the next morning. My trigger has been fine and all the damsels except one, and he seems to be gasping for air but my ammonia levels are nothing so im a bit confused on what might be going on. I just did another water test and the parameters are exactly what they where yesterday.
