I added a Tennenti Tang on Tuesday, and he seems to be very shy. He mostly swims around behind the rock work. I've tried feeding cyclopeze, mysis, spirnula and nori. The only thing he seems to go for is the cyclopeze, but very scarcely. He stays behind the rock and when it blows to him he eats a little bit, but not much. Do you think he just needs a little more time to adapt to the tank? He looks and seems very healthy, but just seems to EXTREMELY shy. How long does it usually take for them to adapt and open up? Do you think its too early for me to start worrying? Any help is good, Thank You!
