Mushrooms and there Care questions

Thank you so much! I will take my poor little guy that is just sitting on the sand and put him onto a rock tonight I am sure he will be much happier I think I will take my poor droopy shroom and move him too I don't think he is liking the bright light to much, everyone else seems just happy and fine

Do I need to feed mushrooms some sites say they need supplimental feeding some say they don't if so what do I feed these little guys?

THANK YOU SO MUCH to all of you for helping me out
