I got three beautiful female paradise gourami at petsmart. The woman helping me was great, she and I were able to sort out the right fishies, and she was upfront and asked if I knew how to tell the females because she didn't. I really appreciated her honesty, rather than the previous swipe and dump job I'd gotten at another store.
I also added a 24" plastic ambulia to the back of the tank, it arches up and over one half of the surface, providing a lot more coverage for the gouramis. The new harem has taken over most of the ambulia bunches in that corner, and the males are sorting out who owns the prime begging spot in the front of the tank, and who owns the other tall plant on the far side of the tank.
Soon I am going to be adding live plants to this tank, water sprite for the gouramis and some corkscrew vals along the back for the barbs. Eventually I'm going to add a small shoal of panda cory cats, I'll probably build a 'beach' for them in the front corner of the tank and ring it with some java moss.
