btw, its not a blue gourami, its a neon blue dwarf gourami. these get to like 2 inches long or something whilst the blue gouramis get to like 6 inches long
Hi, as stated previously your fish is indeed a dwarf neon blue . The correct ratio is 1 male to 2 females. They are territorial. The female is almost all silver with slight stripey markings. They also like floating plants to build a bubble nest for mating.
Your fish looks a little down in the dorsal, water stats ok?
