^agree.
I'd look at two clowns, one firegoby and maybe one small peaceful fish.
Maybe a clown goby, Jawfish or yellow watchman goby.
The built in typeAnemones need a tank with good lighting and stable parameters. I always say 6-9 months before you add them. But I know others have had success adding them earlier.
Better safe than sorry. What lights do you have?
Nice FW tank. Love pearl gouramies.
