I can’t find my long nose tang for 2 days. As you can see by this being post #2, I am a newbie. First tank and I started with a 300 gal system (200 gal 4 side viewing and 100 gal sump). I put a yellow longnose in a week ago and he seemed to fit right in with 3 yellow tangs, 3 regal tangs, foxface, flame angel, 2 clowns, coral beauty, sailfin tang, large purple tang, large clam, long spined black sea urchin,2 sand sifting stars, 6 shrimp, bubble tipped anemone and assorted corals. No remains that I can see and the tank is covered. I have mesh filters in the overflows so he is not in the sump.
