My terrarium - update and all species added

[Longroots]

My terrarium so far has been pretty successful.

I've added a Lepanthes Pilosella, Lepanthes 'Coral Butterfly' (no idea on its crosses), Aernagis Pumilio and Anoectochilus Roxburghii Hayata 'Hong Sia'.

The other species are:
Restrepia Falgenbergii
Stelis Stevenosii
Masdevallia Measuriana
Dracula Lotax (lost a leaf as a small amount of wet moss rotted a leaf).

All orchids seem happy overall so far other than the Stelis which wasn't particularly happy to begin with.

The Lepanthes Pilosella has a new small growth from its vine it seems, and the 'Coral Butterfly' seems to be growing its roots more. Humidity doesn't seem to be a problem at all.

However, there has been some mould out breaks. I've used hydrogen peroxide 6% to keep it at bay which seems to have killed it but obviously it comes straight back. I also think this killed the Springtails so today I added a huge batch so hopefully they'll sort the problem, but they didn't last time.

I have ordered a very small fan that I'm hoping will fight the mould off but I'm not sure it will and I'm concerned it will affect the Lepanthes poorly.

Anyone else have experience with killing mould off in terrariums?
