Ehh. Well no rainbow sharks....... They need a 48" tank. 55 gallons. And only 1 dwarf gourami in a tank, unless you get a male and some females, but females are rarely sold! So it would be a good idea to start a thread asking about stocking input. A basic 36 gallon tank would consist of
1 top center piece(dwarf gourami)
6-8 bottom dwellers(Cory cats or kuhli loaches)
6-8 middle level schoolers
6-8 top level schoolers
1 or a pair if a other solitary center piece( apistogramma, ram)
Depending on wht ya like, you could try
1 dwarf gourami
6 panda Cory's
8 rumynose tetras
6 harqualin rasboras
2 German blue ram
Sorry about the rainbow shark, I too really wanted one, but after many questions and reasherching I found my tank(37 g) is not suitable. I also would possible rethink the dwarf gourami. They have been very unhealthy and nearly 1/3 of the stock has had dwarf gourami disease lately which is incurable and fatal. A honey gourami would be a good alternative, and I think you could have 2 of those
