Well my 29g planted has been up and running for 3 months now. I had my first fish death this morning.
Woke up and found my female dalmation molly dead on the gravel under one of my plants:(
All other fish seem very healthy, energetic, and also they all ate normally this morning.
Did a water test
nitRATE less than 5.0 but definatly not 0
I have never had a nitRATE reading above zero in the 3 months the tank has been up. I change my water every week. Is the elevated nitRATE the reason why I lost a fish?
