Longtip toadstool

[Dkim]

Hello..
This japanese longtip leather coral is pretty much done?
It was green. Now to completely white.
What is All this brown stuff on the leather? Some kind of disease?
It is still in shape, but no reaction and white.
All my other 5 toadstool is doing well.
Just this one is not doing well.
I think my puffer bite the longtip, maybe that is why? Thx.

Current parameters?
The dark makes me think detritus built up and it has started to rot. I would dip in something like coral revive or an iodine and place in higher flow.

I did not test recently. All other corals are in good shape.
I do water changes every other week 30 percent.
5 years old tank.

Funny thing is I collected different kind of toadstool, this is 6th one. Just this one do not do well. 5 other toadstool is in good shape.
One in the middle is the dead one.

He might like different conditions than the others. Maybe less light or more flow.
I would still proceed with what i recommended above. Hope he pulls through hes one of my favs.
