The side they don't go on has less current than the other side. Actually my whole tank is rather low flow. It only has a Mag9.5 throttled down to 2/3 and Koralia 2's (one in each corner). The fish will venture over to the other side for a moment but swim right back to the other side. I guess the only good thing is that all my fish really get along to live so closely together without fighting.
