Bleached mushroom and dying yumma

[maleks.reef]

Hello. About 2 weeks ago I got my first yumma mushroom alongside a random common green mushroom. Within the first 48 hours of placing them on the sandbed, the green mushroom was fully bleached and the yumma had lost most of its tissue with only the foot/base remaining. My guess is that it was too much light for them although I have other mushrooms doing just fine at the same level. I have moved them to a dark shadowed area of the tank ever since and both seem to be just existing for now, no clear recovery but no death either.

The green mushroom detached from its rock yesterday. Does this mean its too far gone? Should I place it in a cup with some pebbles in a low flow area in hopes it reattaches?

Thanks all.

(no parameters since all my kits expired and I didnt bother to get new ones. The tank is a 4 month old bowl with softies, leathers and inverts, all doing fine thankfully.

As per usual, pics might help, pref under both white and blue, and tank parameters are pretty essential.

What sort of lighting?

I would definitely get the shroom in a cup with some pebbles and try.

What are the specs? Yumas are very hardy so there has to be a specific reason for bleaching out.
