Gold Dwarf Gourami (Colisa sota) 2-3 cm

Overview

The Gold Dwarf Gourami, Colisa sota, is a striking colour form of the dwarf gourami group, prized for its warm golden body tones and calm, personable nature. At 2-3 cm, these juveniles are ideal for aquarists looking to grow out a beautiful centrepiece fish in a well-planted tropical aquarium. Their compact size, gentle temperament and attractive colour make them a popular choice for community setups, especially where a peaceful, lightly stocked tank is the goal.

Like other labyrinth fish, dwarf gouramis can breathe atmospheric air using a specialised organ, which helps them thrive in warm, well-oxygenated aquariums with access to the surface. They are best kept in mature tanks with stable water conditions, plenty of cover and a calm environment. With the right care, they develop into engaging, interactive fish that often recognise feeding time and spend much of the day exploring plants and floating cover.

At Tropical Fish Co, we select healthy live stock and pack with care for a smooth journey to your door. Every order benefits from our live arrival guarantee and fast UK delivery, so you can buy with confidence.

Care at a Glance

Origin & Natural Habitat

Dwarf gouramis originate from South Asia, where they inhabit slow-moving waters such as ponds, marshes, ditches, floodplains and gently flowing streams. These environments are typically warm, shallow and densely vegetated, with plenty of surface cover from floating plants and overhanging vegetation. Water conditions in the wild can vary seasonally, but the common thread is calm water, low disturbance and abundant plant life.

The gold colour form seen in the aquarium trade has been selectively bred from the dwarf gourami complex, making it a vibrant ornamental fish while retaining the species’ natural preference for warm, sheltered habitats. In the aquarium, recreating this environment with live plants, driftwood and floating cover helps reduce stress and encourages natural behaviour.

Tank Setup & Water Parameters

A well-planted aquarium is the best home for Gold Dwarf Gouramis. They appreciate subdued lighting, open swimming space and plenty of hiding places among stems, roots and broad-leaved plants. Floating plants such as Salvinia, Amazon frogbit or red root floaters are especially useful, as they provide security and help diffuse bright light. A gentle filter flow is important; strong currents can make these fish uncomfortable and may prevent them from feeding confidently.

For a single fish, a tank of at least 60 litres is recommended, though larger aquariums are always better for long-term stability. If keeping more than one dwarf gourami, careful planning is essential. Males can be territorial, so it is usually safest to keep one male with one or more females in a suitably sized, heavily planted tank. Stable water quality is vital, and regular partial water changes will help maintain health and colour.

Ideal water parameters: temperature 24-28°C, pH 6.0-7.5, with soft to moderately hard water preferred. As with all tropical fish, avoid sudden changes in temperature or chemistry. A mature aquarium with a fully cycled filter is strongly recommended before adding these fish. Because they are labyrinth fish, they will occasionally visit the surface to breathe air, so ensure there is always easy access and avoid sealing the tank tightly without ventilation.

Good maintenance, consistent feeding and a calm environment are the keys to success. These fish are not difficult once established, but they do best with attentive care and stable conditions rather than frequent rearranging or aggressive tank companions.

Feeding Guide

Gold Dwarf Gouramis are omnivores and should be offered a varied diet to keep them healthy, colourful and active. A quality tropical flake or micro pellet can form the staple, but this should be supplemented regularly with frozen or live foods such as daphnia, brine shrimp, mosquito larvae and bloodworm in moderation. Small, protein-rich foods help support growth and condition, especially in younger fish.

Feed small amounts once or twice daily, only what they can consume in a couple of minutes. Overfeeding can quickly foul the water, so it is better to offer modest portions and maintain excellent water quality. A varied diet also helps prevent nutritional gaps and encourages natural foraging behaviour. If your gourami is shy at first, floating foods and feeding in a quiet tank can help it settle in and eat confidently.

Tank Mates / Compatibility

Gold Dwarf Gouramis are best kept with peaceful, non-nippy tank mates that will not outcompete them for food or stress them with constant activity. Suitable companions include small rasboras, peaceful tetras, Corydoras catfish, Otocinclus, kuhli loaches and other gentle community species. Shrimp may be kept in larger, planted aquariums, though very small shrimplets may be at risk.

Avoid boisterous fish, fin-nippers and aggressive species such as tiger barbs, large cichlids, many livebearer bullies and fast, highly competitive feeders. Other labyrinth fish or similar-looking gouramis may also trigger territorial behaviour, particularly males. If keeping multiple gouramis, the aquarium should be spacious, heavily planted and carefully monitored. In general, the calmer the tank, the better these fish will display their best colour and behaviour.
