Which Mushroom coral? getting sick any ideas to help greatly appreciated.

Hi all, i bought a mushroom coral 3 weeks ago, it seemed happy for the first week on sandbed, then has gone down hill since. It has spit out its zooxanthellae and shrunk looking bleached out. its in a 20 g tank, 1.024 salinity,nitrite 0, nitrate less than 10, ph 8, GH 180, KH 180.

Can anyone help with suggestions?

Ive got blue and red mushrooms, and orange ricordea yuma which are growing well and look happy.

 

heres a pic of the blue mushroom, before and after.

Since you say it spit up it's bacteria and is bleaching it seems to be a light intensity problem.

Thanks for the reply, the bigger mushroom in the picture died last week , i did place the rock into a shaded part of the aquarium, and reduced light from 12 hours to 9 daylight hours. It seems to have helped as one of the 3 left is colouring slightly, and opening up now.
