At one point before I shut it down I had in my 29:
Small purple tang
Pair of snowflake clowns
Pseudochromis
Midas Blenny
Lawnmover blenny
6 Line wrasse
flameback angel
I do not recommend overstocking AT ALL. There were situations behind the larger fish such as temp housing and what not but this trashed my water quality. Id only keep a pair of clowns and one more fish like a 6 line or blenny MAX.
