HELP!!! 45 gallon stocking

[mark2103]

So I have a 45 gallon tank with
2 inches of sand
30 Pounds of live rock
It is 36inx24inx12xin

2 occellaris clownfish
1 firefish
1 yellow watchman goby
1 tiger pistol shrimp
1 peppermint shrimp
1 Skunk Cleaner Shrimp

I was wondering how many more fish I could add and suggestions for cool and fun fish and corals for a reef noon like me.

Thank you!
