two spot bristtle questions?

i have a 55gal tank, cycled for a month with live rock only... and parameters is ammonia is 0, nitrite 0 and nitrate around 15... my first fish is a two spot... i acclimated it before i put it in tank... but it always hiding behind rocks and tryin to swim only in dark areas...eg. caves etc. and its not eating yet...
what is this behaviour means??? any ideas guys???

 

Hey, i have a striped bristletooth tang. When i first got it, she was very timid and shy, always hiding. Took her about a week to become adapted to me and my gf even though she is still a timid fish. However, i noticed that my tang immediately would pick at the rocks for algae and plants to eat. If your tang is picking at the rocks, this is a good sign.
Any pics?

heres mine

 

thanks fo the reply sterling... much appreciated... sori got no pic yet..ur tang is rili A class! mine has blue eyes and still has yellow tail... sooo i tink its still young!
ill wait a week and see what happen with its behaviour!
cheers mate!

 

alright dude, keep me posted. I really wanna see you BT tang. I think they're great. Post a pic ASAP if possible.

 

agreed. I'd love to see another one just like ours. I've noticed especially with her that Bristletooths seem to have a tendancy to be a lot more of a laid back species of Tang in comparison to say our former naso, and hippo tangs?
