What are labyrinth fish?

Labyrinth fish goes by the name of Anabantoidei, which is a suborder of Anabantiformes. It contains at least 18 suborders with around 160 families of fish of all sorts and sizes, most of the labyrinth fish species are betas and gouramis. It is different from other fish for its respiratory organ, named the labyrinth organ.

What makes labyrinth fish different?

Labyrinth organ

The labyrinth organ is behind fish’s gills and is similar to the lungs. The organ allows them to take in oxygen directly and helps them absorb oxygen into the bloodstream. But the labyrinth fish is not born with a fully formed labyrinth organ. It is gradually formed as the fish grow up. And the organ is finally fully formed until the fish becomes mature.

By the way, the oxygen concentration of the water around the fish’s growth environment determines the size of the organ. And the two are negatively correlated. For example, if the labyrinth fish is in low oxygen areas, its labyrinth organ tends to be larger and more complex than that of those in rich oxygen areas. Nevertheless, although labyrinth fish can breathe via gills and labyrinth organs, the fish will breathe via the organ most of the time after it is fully formed.

Bubble nests

Labyrinth fish are the builders of bubble nests. The male fish usually blows bubbles to form a nest in low current areas. But the size and thickness of nests are not all the same, because it depends on the preferences of builders – male labyrinth fish.

The accountability of males and females is clear. Female labyrinth fish take charge of laying eggs, while the males are responsible for defending the nest once eggs are laid. Besides, males also need to defend and raise the young and keep them out of danger from other fish.

There is one interesting thing to share! If an unaccompanied male builds a bubble nest, it generally means that the male fish is satisfied with the living environment. That is because factors, including changes in surroundings, the introduction of another fish, or changes in atmospheric pressure, will trigger the behavior of building bubble nests.
