I have never paid much attention to them, but I ran across a few photo's today that made me interested. First off, what is the difference between the two? How are their requirement different? Also, how aggressive are they? I'm not wanting anything like Xenia which can overtake my tank. If they can be isolated easily then I might give them a try.
On that note, what are some of the more sought after varieties? Any photos would be appreciated.
