What brand of suction cups do you use? I tried anubias attached to suction cups on the sides of the tank but the cups let go after awhile. Must be strong cups to hold the drift wood, but it does look nice.
I keep tetras with my hystrix- black skirt and blue redfinned tetras. The not-so-smart ones usually disappear with in the first couple of days. Three plus years later and there are still a few left.
If I had a tank like that in my office, I wouldn't get any work done...
