Hi, I'm new to the hobby also...I'm planning to get my tank this weekend, it'll be 40g-50g. Lol, the 2 stores I went to a few days ago gave me incorrect info, which seems to be a common thing. So, I'm waiting to have my fish list approved by other more experienced posters in my fish compatibility post.
From what other posters have told me so far, it seems good. Not the tang though, they need a huge tank, or you'd have to get a juvenile & upgrade to a bigger tank when it gets bigger.
