I used the black 1/2" plastic hardware cloth from Lowe's for the moss wall on my nanocube. My only regret was that the clear suction cups I used turned white after extended immersion and really stood out until the moss grew over them. My kuhli loaches and cherry shrimp hide in it all the time, but I haven't seen one of them get stuck.
