Haliptilon sp

[SpinyLobster]

I want to add some red to my tank and came across this kelp(?) at Live Aquaria. Is this a good plant to start with if you're new to salt water plants?

Does it have any special needs and more importantly is it invasive? It will be going into my mixed 29 gallon reef with 175 watt MH and 75 watt VHO accintics.

Thanks.
