the tetras should be ok as long as they're not tiny. check into the types of gourami's you get. Many gourami's can get very large and many can be very aggressive. I have a gold gourami that I would definitely not recommend with angels. I think the dwarf's would all be pretty good. Each fish has it's own personality though so you can find good and bad in each species. Kyle
I would get at least 5-6 of the tetras. They work best in schools of that size minimum. 1 Angel and possibly just one gourami. I would also add a bottom feeder as well, but that is just me. Maybe a nice small school of 5 cory catfish?
