Dwarf Croaking Gourami

A tiny member of the fascinating gourami clan, and one best kept in a nano-size tank. Aaron Norman


Like the Croaking Gourami, this species makes audible clicking sounds. These fish are tiny and delicate and are ideally kept in a “nano-tank” dedicated to their needs with other small, mild-mannered species.

Family: Osphronemidae

Other common name(s):

  • Pygmy Gourami

Native range:

Habitat: The Dwarf Croaking Gourami prefers an aquarium well planted with broad-leaved plants, such as Echinodorus, as well as a cover of floating plants. Provide ample hiding places in the form of driftwood, rocks and inverted flowerpots. A dark substrate will make them feel comfortable and show off their colors.

Maximum length: 4 cm (2 in)

Minimum aquarium size: 8 L (2 gal)

Water: Freshwater 22 °C (72 °F) - 26 °C (79 °F)

General swimming level: Mid-level


Omnivore. The natural diet of this fish consists of tiny insects and insect larvae. They will accept meaty foods in the aquarium, including flakes, freeze-dried, frozen and live foods. Occasional meals of herbivore-type foods will be taken.

Aquarium Compatibility

T. pumila is a peaceful, small gourami that may become aggressive during spawning. Keep in groups of one male to two or more females.


The male builds a bubblenest under a large leaf and tends to the eggs and fry.


They should only be housed with fishes of similar temperament and size, as more assertive species will outcompete them for food. Known fin-nippers, such as Tiger Barbs or large danios, should also be avoided.
