Do Gouramis have labyrinth organs?
Betta and gourami fall into this category. As I said earlier, gourami and betta take oxygen from the air with the use of their labyrinth organ. This organ is an extension of the gill plates (bone that anchors the gills) and is made of many folds of bone.
Is a killifish a labyrinth?
Killifish in Aquariums The killifish is a small fish even in the wild where they are predators, mainly on insect larvae. But unlike a betta, special attention must be paid to the water conditions (remember that the betta is a labyrinth fish and is not so concerned with water conditions).
Is a betta a labyrinth?
Bettas and Gouramis make up the lion’s share of labyrinth fish species. Labyrinth fish are native to Africa and Southeast Asia, residing in areas where high temperature and low water depth result in low oxygen saturation in the water.
Which fish have a labyrinth organ?
The Anabantoidei are a suborder of anabantiform ray-finned freshwater fish distinguished by their possession of a lung-like labyrinth organ, which enables them to breathe air. The fish in the Anabantoidei suborder are known as anabantoids or labyrinth fish, or colloquially as gouramies.
Is arapaima a labyrinth fish?
The fish is an air breather, using its labyrinth organ, which is rich in blood vessels and opens into the fish’s mouth, an advantage in oxygen-deprived water that is often found in the Amazon River. This fish is able to survive in oxbow lakes with dissolved oxygen as low as 0.5 ppm.
Do Gouramis have lungs?
Gouramis are a group of fish in the families Osphronemidae, Helostomatidae and Anabantidae. They have a labyrinth organ that acts sort of like a lung, which allows them to breathe air at the surface. In nature this adaptation enables them to live in shallow, stagnant, oxygen-poor water.
Is corydoras a labyrinth fish?
Labyrinth Breathers: Corydoras prefer to live in cooler waters but possess an auxiliary breathing organ that enables them to survive in those shallow pools of low oxygen warm water. You can see them come up to the top to breathe. Corydoras make excellent scavengers, but they are also good looking fish.
What is labyrinth fish?
labyrinth fish, any of the small tropical fish of the suborder Anabantoidei (order Perciformes). Labyrinth fishes, like most other fishes, breathe with their gills, but they also possess a supplemental breathing structure, the labyrinth, for which they are named.

Why do gouramis kiss?
The Kissing Gourami gets its name from the way it will kiss other gouramis and other fish in your tank. They are not kissing but they are in fact acting aggressive and having a showdown. When they do this it means that one is trying to establish dominance over the other.
Why do Corydoras shoot to the surface?
The water in these is warm and shallow, and holds less oxygen. Most fish wouldn’t be able to withstand this, but Corydoras can gulp air from the surface and use their posterior intestine to extract oxygen from it and pass it into their blood where it’s needed.
