Whats wrong with my fish ??

[FWC]

So something seems to be affecting my fish...

They more or less look the same ,perhaps a bit more muted in color ,but nothing major.

However they are acting a lot different. They are all flashing against the filter tubing or on the sand ,and they all look like they want to be cleaned by the chromis. They will flare their fins and open their mouths to be cleaned ,but sadly chromis don't clean fish.


Also my water seems a little off. Not full out cloudy ,but not quite crystal clear like it should be. Its clear ,it just seems...off....
