The Labyrinth is located above the gills and consists of skin folds, called Lamelli , which are filled with blood vessels, through which oxygen can be absorbed from the air. This feature allows the Labyrinth fish to survive in water with very low oxygen levels. In general, the Labyrinth fish are not difficult to keep. The tank should be well lit, but not be overly bright. The substrate should be a dark color with dense plantings including many floating plants.
Some genera prefer the safety of caves.
Feeding is not a problem as all flake food is readily accepted. In nature Labyrinthfish appear to prefer very weedy rivers, streams and ponds. Some are even found in irrigation ditches, flooded rice fields and even polluted waters. Aeration and filtration is not needed, especially with the bubble nest builders. As you can see most Labyrinthfish are very undemanding and can be placed in just about any community tank setup.
