Sphaerichthys

Sphaerichthys is a genus of gouramis native to Southeast Asia known as chocolate gourami.^[2] These species live mostly in blackwater rivers/swamps with acidic water. They have dark-light brownish hues with the exception being the female of S. vaillanti which can be dark reddish brown with green-dark blue/black stripes. They are shy fish that are hard to find because of their camouflage which when in action makes them look like a dead leaf floating along the river.
