I am kicking around adding 4 or so more ( have 1 now) cardinals then maybe order in 20 chroumis. I have 2 now that are starting to get big, the one has a lot of blue on it and looks good. I have learned the key to keeping them is feeding at least twice a day and feed on the heavy side. The powder blue we got is really active (probably the most active in our tank) and has some great colors. Marine solutions has some nice fish in as well as some nice corals (which is where I got the powder blue). I think I am going to get a green corris wrasse sometime after the first of the year as well.
