Just wondering what type of bright/cleaner fish I can put in my 20L... I know it is limited. I was thinking maybe a yellow coris wrasse, lawnmower blenny and purple dottyback. I have it ran with about 25 pounds of LR, a 20G sump, bubble magus curve 5 skimmer, filter sock, filter pad and sponge so real estate is more my concern here than bio load AND jumping out...
