I have found that artendiella care depends on your ambient air humidity. Higher air humidity, you shouldnt water as much. Lower, you water more.
I have a misting system for mine. These get sprayed 10 seconds once a day in the morning and a cpu fan that pushes air in 4x a day for 15 mins.
These love kudzu. They hang out on it. Eat it. I put a curved L shaped lichen stick on one end and then tilted bark over towards it and the bark lays on the lichen stick. So they hang out on the bark and suspend in the air. They have done incredibly this way.
