I've had them since mid July. They went though their quarantine while I finished the build.
What exactly makes for a stressful environment? There is some foot traffic where their tank is but nothing major.
As far as plants that touch/break the surface, I have 1 and one of those bendable 'jungle vines' breaking the surface at several points. I have some sword plants but they are too short, I'm not sure if the will ever reach the surface. My water is at minimum 14 inches deep. I need to find tall cold water plants. Bare bottom is just not something I want, I'm trying to make it a bit of a center piece. I want something rather natural looking.
This is what my tank looks like right now. I'm not exactly happy with the looks.
