soft corals wasting away....

[mrcopitr]

Hi guys....

I need some advice...I have ( or should I say had)a giant mushroom (rhodactis species) next to a green hairy mushroom. They have been next to each other in my tank since initial set up (9 monts ago). When I got up this morning the green hairy was all rotten away..only shreds of brownish matter left and tonite my giant mushroom is covered in the same brownish greyish matter and wasting away also.....

All my other corals are fine and water paramters are within range....


what is happening...Is my tank crashing???

Please give me your opinion on this

Best regards

Marco
