I have used super glue in some instances with good effect. It grows slow so very little trimming if any. Once every 6 weeks etc. I just break off clumps and shove it into holes in the rock. It's got a rough texture in my tank.Very nice.. i have something similar but a much darker shade of green that grows pretty slowly so I've had trouble identifying it. I did try to push it into a crevice but it just floated out.
How do you secure it and does it require a lot of trimming?
