I was getting ready to treat with FWE and thought I'd feed my tank beforehand. I noticed my juvenile clownfish that I added 3 nights ago was quite lethargic. It's breathing pretty rapidly and didn't eat a single bite. This is highly atypical for this fish, which ate voraciosly in my quarantine tank and in the display every day until now. I'm very worried about this fish and decided not to treat with FWE to avoid putting any more stress on the fish. I think I'll do a 10 gallon water change just in case there is some FWE toxicity in the tank. I tested all my parameters (pH 8.4, salinity 1.026, Ca 400, alk 8.45, nitrate 0, phos 0) and the water remains in good condition and stable. I hope this fish doesn't die, that would REALLY bum me out.
