you wouldn't be over stocked all the inverts would have a very small bio load
zoa's pallys and corals don't effect bio load , and fish would be fine .
when your ready to transfer I would add new sand ,other than that transfer over rock and zoa's pallys coral ect , than all the inverts you can find the 2 candy cane pistols will probably be the hardest to rally up as they'll bury them self's
if using the existing rock you most likely wont see a cycle maybe a slight swing but that should level out by the next day
Fish are like lifesavers
They come in different colors
