I have been researching which fish will be a good choice in my new 30 gal. I am still a long way from getting fish, but I like to look I would really like to get a Maroon Clown. I have heard they have a lot of personality (some good & Bad), and I love the way they look. I would only get 1, since I do want to add other fish. Is this a good choice for a 30 gal tank? And if I got one, should it be my 1st fish added, or last?
