I honestly do not think I could pick. I have a tank with just corals and I enjoy it, but not nearly as much as my tank with both. I love all of my fish's personalities, and I love watching my corals thrive and grow. If you would have asked me this 6 years ago I would have said fish all the way, but 6 years ago i could only keep softies alive lol. Nope, I can't choose, I forfeit!
