A stunning nano species known for its iridescent blue/green eyes, body spots, and ability to make audible 'croaking' sounds. Unlike many anabantoids, they are social and best kept in groups. However, they are efficient micropredators that will hunt shrimp fry and pests like hydra. Requires stable water parameters and dense planting.

Sparkling Gourami Care Summary
The Sparkling Gourami, scientifically known as Trichopsis pumila, belongs to the Anabantoids family group. Adults reach a maximum size of approximately 4 cm and have a fusiform body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the surface, mid-level, and bottom zones of the aquarium and produces a low level of biological waste.
To thrive, the Sparkling Gourami requires a freshwater only aquarium with a minimum volume of 38 litres and a tank length of at least 45 cm. Water temperature should be maintained between 22°C and 28°C, with a pH range of 5–7.5 and a general hardness of 5–18 dGH. A low water flow is preferred. To replicate their natural habitat, the tank should include plants - densely covered, plants - floating, and leaf litter/blackwater.
This species should be kept in groups of at least 4 to reduce stress and encourage natural behaviour. Keepers should be aware that this species is not safe with ornamental shrimp and can be aggressive toward its own kind. The Sparkling Gourami is typically available in one standard form.
Similar Species
Three Spot Gourami (Blue/Gold/Opaline)
Trichopodus trichopterus
A robust, semi-aggressive labyrinth fish available in many color morphs (Blue, Gold, Opaline). Biologically, they are all the same species. Unlike the peaceful Pearl Gourami, Three Spots are boisterous and can be bullies. They are excellent for 'semi-aggressive' community tanks (e.g., with Tiger Barbs, large Tetras) but may harass shy or long-finned fish.
Dwarf Gourami
Trichogaster lalius
A peaceful to semi-aggressive labyrinth fish native to South Asia. Famous for their brilliant metallic blue and red stripes. While generally suitable for community tanks, males are territorial toward each other and similar-looking fish. They are sensitive to water quality and prone to Iridovirus if stressed. Requires access to the surface to breathe.
Honey Gourami
Trichogaster chuna
The smallest and most peaceful member of the Trichogaster genus. Ideally suited for planted nano aquariums. Unlike the aggressive Dwarf Gourami (*T. lalius*), Honey Gouramis are timid and gentle. True Honey Gouramis rarely exceed 5cm. Note: Many bright red fish sold as 'Red Honey' or 'Red Robin' are actually Thick-lipped Gouramis (*T. labiosa*), which grow larger.
Pearl Gourami
Trichopodus leerii
Widely considered the most beautiful and peaceful of the large Gouramis. They feature a 'mosaic' of iridescent spots and a distinct black line running through the eye. Unlike their aggressive cousins (the Three-Spot Gourami), Pearls are generally gentle giants, though males can be territorial towards one another. They are thermophilic (love heat) and require floating plants to feel secure.
Giant Gourami
Osphronemus goramy
The Giant Gourami is a massive, highly intelligent anabantoid that behaves more like a wet pet than a typical community fish. They grow extremely large and have voracious appetites, often completely consuming any live plants in their tank. Due to their immense adult size and extreme bioload, they require massive aquariums and robust filtration.
Scarlet Badis
Dario dario
One of the smallest known aquarium fish, resembling a tiny jewel. Males display brilliant vertical red and iridescent blue stripes. While beautiful, they are known for being extremely picky eaters, often refusing dry foods and requiring live or frozen micro-foods (Daphnia, Baby Brine Shrimp). Males act like tiny Cichlids and will stake out territories.
