if i took a small 10 gallon tank
if i took marimo moss balls & cut them up till they were really small ... ...
split a large marimo half way through.use your fingers to gently spread it out and lay it out flat.lay it on some slate pieces and either try super gluing them using cyanoacrylate super glue or use a hair net to cover it.it should eventually overtake the hair net.
