Hi - I have had my firefish for about 4 weeks now, and it was doing good. Did a water quality test at my lfs
on Sunday, and my nitrates were at 160ppm, and salinity at 1.025. LFS
recommended a 25% water change with only r/o water, provided by them. I did that, and salinity dropped to 1.019, but nitrate remained at 160. Did 1 more 1litre water change, but still no change in nitrates. This morning, fish is hanging at front of tank - usually it hides in its cave under rock, and not interested in feeding. Is this ick?
My tank is a Fluval Edge (6 gallon).
I should add that I got a feather duster from LFS
on Saturday - all water parameters were fine then- only deteriorated after the duster.
