This plant of A. kotschoubeyanus behaves like a astrophytum koh yo. During changes of season turns from bronze to orange, then return with shades of green. Have you news of other similar plants?
I have a seedling of fissuratus that change color, now it's pale green, but it was yellow and orange. As soon as possible I'll post some pictures.
Good news, looks the picture of your plant!
One of my grafted scaphirostris turned its body color in seasons.
It was quite weak and had gone.

Frank, I'm sad for your plant, it was super!
C&D, that Ario is great!!!
So, it is the plant i was talking about, i have some pics taken during last year, the colour change is very funny!
During the first hot sunny days this spring, this plant was damaged by the excess of light, it cannot manage full sun as normal arios can. Luckily the burnt tissues dryed and the plant looks helthy now, ready for new growth.
