Sorry for your lost. I believe that when one of your fish died - its' death absorbed one of your bad luck.

two rays ? thats sounds more than just bad luck :s

daily water changes ? could it be something in the source water thats affecting weaker rays or something ? are the others eating ok / as normal ?

You may want to check your KH (water hadness). If you have public water, during the winter they may up the chlorine or chloramines because of salt run offs from the roads. They also may do some kind of de-ionizing too, that removes most minerals in the water leaving the pH unstable and liable to crash.

Also, some rays differ from ray to ray on the effects of water params.
And you may want to also increase the O2 in your tank.

This happened to me this past winter, the night after a water change 3X on 3 sepperate tanks. 9yrs of my tap water being fine then lost 3 rays (1-19'' male had for over 7yrs, 1-16'' male had for 5yrs and 6'' female pup cb from my female).
