Help! Maybe someone has any information about the lifestyle and nutrition of the three spot gourami (Trichopodus trichopterus) under native conditions or in an aquarium? The same information about close species of fish is also interested.
the three spot gourami is one of the most common species of osphronemids in the aquarium hobby and very easy to keep. General information about keeping them can, for example, be found here: https://www.seriouslyfish.com/species/trichopodus-trichopterus
For general information about fishes, FishBase is always a good starting point: https://www.fishbase.se/summary/Trichopodus-trichopterus.html
They will eat almost everything, and are also largely insensitive to water parameters, especially oxygen levels, as they can breathe air. Congeners of the genus Trichopodus might be a bit more specialized than the three spot gourami but are also in general easy to keep in an aquarium.
The three spot gourami (Trichopodus trichopterus) under native conditions or in an aquarium is omnivorous and mainly consumes zooplankton (e.g. copepods, cladocerans, ostracods), macroinvertebrates (insect larvae) and occasionally detritus and terrestrial macrophytes.
It is the hardiest species of the genus and can tolerate wide ranges of water hardness, pH, temperature, salinity and dissolved oxygen conditions (TropWater, 2014). Its ability to survive hypoxia, moderate subtropical water temperatures and brackish waters can be facilitated by its wide environmental tolerances.
