So "SPS" is pretty broad. What I am looking for, but can't find, is a guide of sorts to the different SPS. What's the difference between a milli and an acro? A digi and a stylo? No really those questions, but just something other than "high light/high flow". Care levels, hardiness, the hundred of other variables. Maybe broken down by type: branching, encrusting, plating etc. So for branching you'd have monti digi on the easy side, going to bird'snest to X to Y to acro for example. Hope I've articulated my thoughts, if not well.
