I bought a perc last night, and my Maroon is giving him hell, so I'm setting up a 20 gal tank for the perc. It is just going to be a fish only tank. I'm going to put astablished live sand, and water from my other tank into it. What type of filteration system do I have to have, and do I have to run a skimmer? Thanks in advance.
