So I got a brissletooth tang a few weeks ago. It constantly graises around plucking stuff but I wanted it to start eating nori. I went to the store and bought some dried nori with nothing on it. I first tried tying it down to a rock. Then tried putting garlic on it. Now I bought some emerald entree and it still won't grab any food I put in. It's eating all the algea on my rocks and sand bed and pooping a crap ton . I just want it to eat what I give it as well. Any suggestions?
