I have a question about my yellow tang fish. I bought it online like 2 months ago and first it was very shy and whenever I come to my room it will hide and won't eat. But after few days it got used to seen me and got used to my tank. I have two clownfish and snails and two scarlet hermit crabs in my tank. This yellow tang is very weird, other fish just swim around and this yellow tang always looks at me whenever I'm in my room. It won't swim around that much it just stares at me all the time. Even in the morning whenever I wake up I see it staring at me. It is more like it's observing me not I'm observing it!At night the same thing whenever there's little light it's staring at me. Also whenever I put my algae scrubber thing it will attack it with it's tail but it won't harm any of the other tank inhabitants. It usually hangs around them. Is this behavior normal for a yellow tang? will i ever be able to put a another smaller fish like a reef safe 6 line wrasse in my tank? or a flame angel?
