What To Add?

[FishCrazyMan]

I have:
1 Male Opaline Gourami (Scared of his own reflection)
2 Gold Barbs
3 Harlequin Rasboras
in a 30 gallon tank.

I want to know what I can add to it.I am planning on adding 2 or more gouramis. Preferably Gold, Moonlight or Pearl Gouramis. I might also add some of the Hegeli Rasoboras. hat do you guys think.

(I have bottom feeders, but I am not adding those to the list)

Oh and could I possibly add a Apistogramma Agazzi Blue Face?

The Harliquins and Gold Barbs should be in shoals of 6 or more. I'd up their numbers, then think about some corys or khuli loaches for the bottom of the tank
