This is a 55 gal with about 5 corals in it. Lights are 4x55w power compacts 2 actinic and 2 10,000ks. Filters are Penguin 330 and a Marineland HOT magnum. Dwarf lions tend to be not as hardy as full sized lions like the Volitans. To tell you the truth i've heard of people having trouble keeping the dwarfs, but once you get one that will live, your set. I've had the fu-manchu for close to a year now and he's doing great. Shrimp would definetly be on the menu for the lions and whatever tiny fish they can fit into their mouths, which can open bigger than they look. Thanks for the great comments guys.
