What pruning techniques can be used to keep the leaves of Echonidorus sp. from shooting up aerial leaves? I would like to encourage low, wide leaf growth rather than narrow, aerial leaves. I have a red e. osirus. Any suggestions? I plan to also increase the blue proportion of the lighting to encourage shorter, bushier growth (since I only have a 14" tall 40 gallon tank.) Any suggestions for this same problem with Cryptocoryne sp.? Dave
