my new NTT has been really inactive recently and hasn’t been eating, probably been a couple weeks since he’s been in the 350 but for the past week he’s just been hiding in the same corner. when we first got him he was pretty aggressive and occasionally nipped at the flagtail but now he kinda lays there in the sand all day, should i be worried? he looks like he’s in perfect condition. apologizes for the **** picture but he rarely gets out so i can’t get any better pictures.View attachment IMG_1585.jpegView attachment IMG_1581.jpeg
