i might not go withthe bubble right away. but if you do, make sure he is up top closer to the lighting.
GSP will do fine also, Zoa's will do nice under your lighting too.
there are many differant types of mushroom out there too, some need a bit more light than others, but they wil do nicly in your tank.
the Xenia, is a very nice "softie" but one you may have to watch ( this inclused the GSP's) they will spread pretty fast, if you decide to do Xenia, i woudl also recommend taking a few pices of smaller loose LR rubble and placeing it near or around the Xenia, this way when they do spread you can either move that frag to another place or trade it in to the LFS for something. same with most
soft corals.
Toadstool's are a nice one too.
if you have not already, you might want to pick up a few books.
the
Julian sprung, "corals a quick ref. guide " is a very nice one.
so is hte Invert one.
if you can find it Axelrod's " a guide to Corals for the Mini-reef aquarium" is another nice quick ref.
