Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

Known for its exceptionally calm demeanor, The Croaking gourami is an ideal candidate for a relaxed community aquarium. They rarely bother other fish and often retreat to safety rather than engage in any form of conflict. Their gentle nature means they can easily be outcompeted for food by faster, more boisterous species.

Diet

Omnivore

In the wild, The Croaking gourami is an opportunistic omnivore that consumes a wide variety of plant and animal matter. In captivity, they will readily accept high-quality flakes, pellets, and frozen foods like bloodworms and brine shrimp. Supplementing their diet with blanched vegetables or spirulina-based foods will ensure optimal health and coloration.

Sex ratio

Flexible

This species exhibits distinct sexual dimorphism, making it relatively easy to distinguish males from females once they reach maturity. Males typically display much more vibrant colors and possess longer, more pointed dorsal and anal fins compared to the females. It is often recommended to keep one male with multiple females to prevent the male from excessively harassing a single female during courtship.

Feeding frequency

Twice daily

To maintain optimal digestion, The Croaking gourami should be fed small meals once or twice a day. It is important to only offer as much food as they can consume entirely within two to three minutes. Overfeeding can lead to severe water quality issues and potentially fatal digestive blockages.

Bioload

The Croaking gourami produces a relatively low biological load due to its small size and efficient metabolism. However, maintaining excellent water quality through regular maintenance is still fundamentally necessary. A well-established biological filter will easily handle the minimal waste produced by a group of these fish.

Flow

Stagnant

The Croaking gourami naturally inhabits slow-moving or stagnant waters, such as swamps, rice paddies, and densely vegetated ponds. They strongly prefer an aquarium with very gentle water circulation, as strong currents will cause them significant stress and exhaustion. Using a sponge filter or baffling the output of a power filter is highly recommended.

Reproduction

Oviparous

During reproduction, the male of The Croaking gourami constructs a complex bubble nest at the water's surface, often incorporating floating plant material. After a delicate courtship embrace, the female releases eggs which the male meticulously collects and places into the nest. The male then fiercely guards the nest and fry until they are free-swimming, at which point he should be removed to prevent him from eating them.

Compatibility & tankmates

This species is generally very peaceful and makes an excellent addition to a community aquarium. They get along perfectly with other similarly sized, non-aggressive species that share similar water requirements. It is best to avoid keeping them with overly boisterous or large fin-nipping tank mates that might cause them stress.

Tank level

Middle

The Croaking gourami primarily occupies the middle and lower strata of the aquarium, rarely visiting the very top unless food is present. They enjoy navigating through dense vegetation, driftwood tangles, and rocky caves near the substrate. Ensure the lower half of the tank is well-decorated to provide them with ample territories and hiding spots.
