My tank is just now getting set up. It has water and live rock...building sump now. Anywho, after it cycles, my first fish was going to be a clown or two. My tank is going to be a FOWLR (90 gal tank w/ 55 gal sump). My lighting is 4 T5 bulbs w/ two 6,500k bulbs and two blue acintic bulbs. Can I get a nem w/ that lighting? If so, should the tank be established for a while before I get one? If that is true, if I get clowns now, will they use the nem once I get it (later on)? Thanks!!!!
