good point Brian. those do very well in retf vivs. i think brian was making more a generalization. but as with anything, there are exceptions to the rule
as far as overplanting, i only recommend planting light to people who are new to the vivarium world. for those people who have experience with plants in a viv or terrarium setting, i would say go for it. i believe people who are new to the whole frog/viv thing can find it overwhelming when all of a sudden they get a massive growth spurt after the acclimation period and they suddenly have this jungle on their hands, as well as trying to care for their new froggie friends.
