Trying to get my Purple tang to eat prepare'd food but he rather graze on algae all day. That's a problem since I don't have enough algae for him to consume on a daily basis. I tried seaweed, frozen veggie mix, frozen brine shrimp, and frozen blood worms all dipped in garlic. He only put in some interest with the seaweed, taking a few tear at it then proceed to look for more algae. Can anyone give any recommendations?
