Also known as the moonbeam gourami, this silvery fish can be an eye-popper in pet stores, but grows large (up to 6 inches) and needs a larger aquarium then most aquarists can dedicate to it. It is nonetheless peaceful for its size and can be a beauty in a larger aquarium. pH should be on the neutral side, and temperatures should be between 76-86 degrees. it should be alright with dwarf gourami and i dont think it will harm your neons, but if you get a pair and they breed, thats wen they might harm them becuase they get terrorual.
