Clownfish lying on the bottom and gasping

[brodyquinthooper]

I just did a water change and now my clownfish is lying on the bottom of the tank gasping. The other fish seem fine. Does anyone know what I can do??

Difficult to say - was the fish 100% fine before the water change? What percentage was the change? Did any of the water quality parameters (temperature, salinity or pH) changed markedly after the change?
