Yea, actually the guy who sold me the my last 2 advised I use rodi also. Not only were all his fish really healthy, beautiful, and free of peppering, his fish were with plants and gravel, which from what I have seen is an accomplishment. The albinos he sold me were the ones showing ich, are a tad bigger than my original 7, but now are the dominant ones in the tank. Not bullying but at the top. Always hungry too.
