I have a 1 year old setosa that has always done well. Suddenly (overnight) it's almost all white and the orange/red skin is flaking off.
All other corals in the tank are doing quite well. There's been no new livestock in this 1.3 year old 33 gallon cube tank for many months. No lighting or other changes. Weekly 10% water changes. Parameters stable.
The only change I can identify is that a bizzaro cyphastria (8 months in tank) has gotten to within about 1/2" of it. Could the cyphastria have caused this?
FYI, visible in the photo is some cyano I've had for a few months now (I manually remove it every few days, if it's contacting corals), also some coraline algae, and just off to the edge my tuxedo urchin that has been in the tank 7 months and never hurt any corals, including the now dying (apparently) setosa.
On the same rock formation (but NOT nearly as close by) and doing fine is a blue staghorn, Burning Banana Stylocoeniella, purple stylo, and birdsnest.
