They love lots of places to hide and some plants which are soft not scratchy (more of a concern if plastic) hanging near the top of the tank.
I always leave a couple of different plants, and moss strands now that I have some, loose near the top, opposite side from the discharge flow, in the most still area of the tank. All of mine love resting and sleeping in the crook of the plant stems. Also they seem to like to sit on the Banana Plant leaves.
