Adding Live stocks to

hello Guys ,

I have a 29G BareBottom which is running for about 8 months now.
All stable param and have 3 small fish and 2 colony and few frags

Fishes:
1 - occillaris clown fish
1 - Royal dottyback
1 - purple firefish

Inverts:
1 Skunk Cleaner shrimp
1 blood red fire shrimp
1 emarald crab
~6 Snails
6 Scarlet hermit crabs

Corals:
Colony of green pearl bubble coral
1 large frag of green octospawn
1 large frag of branching hammer coral
1 frag of golden hammer
1 frag of orange coral
1 frag of gigantic green hairy mushroom
1 frag of candycane

Now i need advise on adding few fishes and few corals?
can i add bit more expensive corals

i am not interested in anemones so i basically have two island of LR and i am interested in isolating right side for Euphyllias which is what i am doing and 1 really huge 1 live rock(15 lbs) standing tall and good on the left side which is basically empty other than supporting my bubble coral and few small zoas on a isolated rock in the middle of the tank.
My mushroom is glued on a rock that is sitting at the bottom middle of my tank.

my old aquascape was amateurish so it looked clumsy and out of space for anything but now i understood and corrected and my tank looks pretty empty and has lot of space.


Advise!!!! suggestions please !!!!
