i cant figure it out, every time i get the common
pulsing xenia in my tank it takes a "roller-coaster ride" doing really good then bad then good then bad
then it all melts away? i have some elongated xenia thats doing fine as well as sps, lps, zoas, shrooms everything else is doing so good....

i dont think its a flow or lighting problem bc it was in at least 5 differant places and levels in my tank and it all dies, just that kind, i did just lose a leather toadstool i think theyre called. looked like it was rotting or somthing ill try and post a pic of that if i can as well
any insight would be a great help! im not going to get any more but am conserned there might be somthing else wrong. all my
water tests are comming up fine and as i said all other corals/fish are doing great
