Giant Mushroom Cup dying?

[JurisHP]

I have had a HUGE Giant Cup Mushroom for a while now and he has always been out, healthy and thriving. Until recently, when I upgraded my lighting to 3 Radion XR30 pros (I replaced 3 XR15's).

Could the more intense lighting be the culprit?

It could be... What does your lighting schedule look like? Intensity, duration, etc?

Most likely, did you slowly acclimate your tank to the new lighting by ramping up the intensity over a few weeks? That's usually the best way to ease them into it. I'd cut the intensity and photoperiod for a bit to see if that helps.
