Starting and keeping a freshwater planted tank cause a serious change in human behavioural patterns - looking dreamy eyed at your tank for hours on end; phoning your loved ones (or anyone!) in the middle of the night to tell them about a new leaf, a new runner about 1mm long, ... which you have just discovered; not buying new clothes, furniture etc. because your tank REALLY needs that new light, filter,
CO2 system, etc.... Oh well, maybe you won't get hooked so badly.
