After some more thought I have decided to stick with a macro/Palau nepthea tank. I put another larger piece of nepthea and dragons breath in my tank from my girlfriends tank today. I will just try to fill the tank with really nice macro and use one of my 5.5g sump section that has the LEDs over it as a nepthea prop tank. It is one of the only soft corals I have ever liked, so I will go with it and try to produce a bunch of heathy mini colonies.
