Dying, dead or just a phase?

[marcusbacus]

My leather green was just fine until a week or so ago, when it started to change colours a bit turning into something more like purple-ish which turned into a dark shade very fast. I'm used to leathers peelings, but I think this is more serious as it seems that just its trunk has survived so far and there's no sign of green tissue anywhere. I have Seachem Dip if needed. Nothing has changed in the tank. I added 2 images, one from October (it was even bigger than that lately) and one of today.
My guess is that it's 99% gone.

If it doesn't usually turn purple when it sheds, then dip it

I think it's the first time it's shedding here, it shrunk a couple times but it was just for a few hours the most. I might dip it anyway. The other leathers I have don't change colours like that when peeling, they just have the brown skin peeling off although some look pretty beaten while that happens.

Just checked it again and it seems to be melting, almost all the branches are gone after some poking, the trunk is still resisting though.

Definitely dead. Not a single fragment left.
