I've got some red dragon tongue, and a red either gracilaria or codium. not sure what really, kinda rubbery. but both bright red. like a couple snips i gave to RBTA at the last meeting. and some green halameda. i see a little sprout of red grape popping up again. if it takes off, i can snip a branch of that off too, but later. it comes and goes. when the tank is dirty enough they rebound, when its too clean it seems to disappear. i must be in dirty tank mode again. the halameda needs lots of calcium.
you will need to get them to anchor to a rock. then they stay put and grow nice. and later multiply. new ones will pop up all over.
also some fine feathered calerpa, and taxifolia, and a little bit of razor, and prolifera, all green. i just pulled a bunch out a couple weeks ago, so its a little thin. right now. and some chaeto. and i just trimmed that back recently too. i seem to have a varitable weed garden going here. but they are interesting. like they say in gardening, a weed is nothing more than a plant out of place.
whatchu need?
