Yah... still. After I dropped it and shifted it a few time today. Don't think it will recover soon.
Guess what, I didn't manage to buy the glue so I tried your method and used a stocking to tie the single mushroom to a rock. Will check it out tomorrow to see if it had sticked on or died.
Btw, i think my blue tang is dying. It kept laying down to rest but not dead yet.
