feeding new yellow tang

I've had my new yellow tang for 4 days now, and he is still very shy and stressed. He has horizontal white stripes down his sides, which I know are indicative of stress.

Anyway, he won't eat anything I put in the tank - not flakes, frozen brine shrimp, or mysis shrimp. But he will graze on the purple nori that I put on a clip in his tank. My question is this - if I continue giving him the nori, will this prevent him from learning to eat the other food? Should I let him get a little hungry and try flakes, or should I leave well enough alone?

 

You want to keep giving him nori as it is the normal main food for tangs. They are herbivores that accept meaty and other foods.
I use broccoli, hikari brand algae wafers sometimes and flakes when I'm out of town but, mainly meaty and veggie clip with seaweed. It's dirt cheap from ebay:
Nori Dried Seaweed 50 Sheets 7" x 8" Marine Fish Food - eBay (item 250433196102 end time Jun-26-09 20:24:37 PDT)

 

keep the nori going jjk. he will eventually come around to the other stuff. but he definitely needs his veggies. thats a staple of theirs

 

I just went through about the same thing. The Tangs are natural grazers and can go for a while without eating food that you are trying to give him. Just stay persistent without adding too much of a bio load and he will get there. Good Luck
