Hi,
I have a Den. christyanum. i had it in the orchid tank for a while. it seemed to have a fungus and each time it put out a new growth the growth soon rotted
i repotted it and took it out of the orchid(arium) tank and almost gave up on it. i let it get very dry and almost forgot about it.
now it is putting out a new growth

and getting regular attention.
and i am not putting it back in the tank for now...
i am not sure if it is blooming size? it is quite small.
