I have a bunch of rhodactis mushrooms near one another in my aquarium, and have for months. The longest standing additions were two green rhodactis, then two orange, one red, and now one blue. Something seems to be killing the orange rhodactis, but only the oranges -- they still have their orange bumps but their base color is going from a healthy looking orange to bleached white. All the others seem to be thriving. I'm quite puzzled because if anything, all my water parameters are both better and more stable than when I put them in the tank. I slightly increased the intensity of the lighting for the sake of other corals in my tank right around this time, and was worried it could be that, but at this point, I don't think that's the culprit, either. They are both placed about as low as possible in the aquarium, and in the past have had no issue using the outcropping of rock they are attached to for shade.
I've added some additional mushrooms to the area, including a few ricordea. Could that be the cause? If so, is there a reason it doesn't seem to be affecting the other mushrooms in the area? Is there anything else I should check?
