Fish stock ideas

[ScubaSteve]

After losing my butterfly and mandarin in a recent ich + mystery disease, I am starting to look for new fish. I am also going to be rebuilding my entire before getting them, so I've got at least a month or two, but I am looking for ideas.

After the rebuild, the tank is going to be a 45 gallon rimless cube (24"x24"x18") with a 15 gallon sump, vertex IN80 skimmer and a Coralife 250W Halide with 2x65W actinics. The tank has no top to it.

Currently I only have a midas blenny and a randall's goby, a pistol shrimp and 2 cleaners. And a LOT of coral. I keep mostly SPS with a garden of rics and zoas in the bottom areas of the rock work and a smattering of LPS and other corals that catch my fancy. I am going to be rescaping to give even more open swimming area.

I am looking for some ideas of new fish to stock the tank. I'm really looking for colorful fish with a ton of personality (trying to replace a sorely missed butterfly) and peaceful. I am open to all ideas!
