So this grew up over the week... At first I assumed I needed to treat for an algae growth (prob do but that's another post). Fortunately this is on a loose stone so I got some pretty good closeups. I bought a 'clump o frag' bits n pieces for $20 at my LFS. most of it died ... but this one fern, normally about 2-4 inches tall, migrated to this rock. It is incredibly difficult to see, but it is still there ... Im guessing .75 - 1.25 mm tall (yeah millimeters... the other was inches). The intriguing part is this bright green .... carpet?... spot on the rock currently ~1" diameter. Anybody got thoughts? I'm noting the density of gray under the green (the rock was solid covered in Coraline algae to start). That causes me to wonder... not algae???
