2 year old 55g salt tank fish are dying slowly...
Fish started to look dusty gray bodies
Maybe a few small white dots not many

Lost 2 angels fish some fin rot before dying
Have one fire goby doesn't seem to have any problems at all...eats like a pig..lol
2 clown fish have same gray dusty bodies maybe a white dot or two but still eating
1 cardinal did get some kind of Popeye and changed color almost to white from dark brown
1 angel fish dusty gray but moving fine and eating well
Did a picture of the cardinal fish

Thanks for any thoughts the water is good quality before this problem...
