The Blue Gourami is a great entry-level aquarium fish for larger community aquariums. This fish is always a fantastic candidate and essentially a must-have in any community aquarium due to its striking colour, and peaceful personality. The Blue Gourami is also a very hardy fish that can tolerate a range of aquarium parameters and being an anabantoid, these fish have a primitive lung that allows them to take gulps of oxygen from the surface to breathe. The Blue Gourami much like many aquarium fish does have accentuated colours due to selective breeding. One of the coolest factors about this species is that it does come in a totally gold form as well which is equally common. Blue gouramis as their name suggests have a wonderful powder blue colour that begins at the head and can transition into a yellow or green colour. In certain individuals, this blue can develop to be incredibly striking with stripes being present as well.
