Opaline gourami (Trichopodus trichopterus)

Opaline gourami is a very beautiful color-morph of three spot gourami (Trichopodus trichopterus). All kinds of gourami belong to Anabantoidei suborder and they are also commonly called as – labyrinth fish.

They got this name first of all due to the additional respiratory organ they possess – it is so called “labyrinth organ”, which is located in epibranchial space and formed by the folds of membrane that covers the bone.

This thin tissue has lots of capillary vessels and as for its functions – it resembles lungs of land animals. If labyrinth fish have no access to atmospheric air, they get suffocated, because their gills don’t provide them with the necessary amount of air.
