No offense, but that stocking is not good for that tank. Unless you have a sparkling gourami, that tank would be too small for a gourami. Also, tetras and white clouds are schooling fish, so you should have at least 6 of one OR the other. And both are pretty active fish, so some will say you shouldn't even have them in a 6 gallon. Otherwise, shrimp aren't much of a bioload, so having a bunch wouldn't hurt much. One last thing, gourami's will eat the shrimp.
