I have had a stable tank for 6+ months. Lately fish have started dieing. There is no obvious disease showing. I test for Nitrite, pH, Specific Gravity, Ammonia. All are good (pH is a bit high). I use only RO water. I change water regularly (every two weeks 20-25%.
I have a shrimp, a choc chip star fish, a larger star fish, and a hermit crab and a few clowns, a yellow tang, angel, a couple of striped damsels, a blue dam.
With in the last few weeks I have lost 2 Monk Idols, 1 anemone, one hermit crab, ...all these loses are from fish/inverts that were doing well for an extended period (not new to the tank).
Water is clear and clean to the eye.
My thoughts is/are 1. two many passive feeders (crab, star fish, anemone, shrimp etc) and there is not enough food left over for them.
Star fish was seen on top of anemone feeding on him...we do not know if this happened post or pre death.
Could the star be eating things like the crab and the Anemone?
Or is this just the natural course of events in a salt water tank?
