imo, e. belem is a superior carpet in almost every tank. the point of a carpet is to be nice and low. plus e. belems leaves curve out after a bit helping to cover up more substrate per leaf then e. acicularis which has relatively straight, vertical leaves.
but they are very similar, and are both true grasses, so you can trim the leaves themselves without killing the leaves.
Makes sense. Sounds like a better choice. There is significant lack of Frank today...wonder where he is and if he caught my email.
I'd love his opinion on plant choice.
