So I purchased this moss from a local fish store. It's not 1-2 grow or anything, but they grow and sell it in house. I'm not 100% sure what they called it. They grow it on what looks to be a stainless steel mesh. So far I've placed it on some driftwood, but decided to move it to a rock tonight. Now what I want is for it to kinda blanket the rock as if in a natural environment. Does anyone know what I should be doing with this? Should I be trimming it short? I don't know if it's growing longer, or just letting go of the mesh, and floating and falling apart. Can anybody help ?
