All my water perimeters are good he was under a rock I flipped the rock so he could maximize the light. I also fed him a scallop.. I bought him when he was bleach white he started to turn that bronze color last week.(which I thought was good).
Ph 8 ,Ammonia 0 ,nitrite 0 , nitrate 0. Phos. .25 salinity 1.022... System has been set up for 6 months, I used the water from a system though that has been set up for 6 yrs... My lights are a 48 inch corallife pro with dual actinic and with two halides.. I was trying not to run my halides because I do not have corals in yet... This a a 72 gal. Tank about 22 inches deep.. Here is a pic today he looks good now what would cause him to shrivel up like he did.. It looked like the tentacles were flat..
