I'm a sps fan. Though it has been years since I had a tank I'm thinking a purple rim monti. A few acros that color up nice like velita and Oregon tort. Maybe a nice pink birds nest. I would like to try a couple acans aswell since they were not to hardy when I first started, now I should be able to find all aqua cultured specimens. And a head or two of frog spawn. I have 2 kiddos and this is kinda OUR tank so I want to make it fun and colorful. The fish I want aswell are a warpaint goby, pygmy hawk. And some sort of shrimp goby with a shimp. Anything more I think will be way overboard if that isn't already. If I went with another tank I would get a 29 cube just for the extra water volume, from what I here the fluvo is quite a good setup though!!
