My tank always has food in it cause I always have live ghost shrimp in it for my bichirs to eat. My NTT is rarely ever seen. He hides in some weird spots... The fish is only about 2 inches and hes in a 120g with a 8" ornate a 7" senegal and a 6" delhezi. Maybe thats why he hides... Before I got the othe 2 bichirs he was all over that tank with the 1 Ornate.
