Powder Blue Dwarf Gourami - Trichogaster lalius : Complete Fish Profile & Care Guide

Table of contents


Powder Blue Dwarf Gouramis are a stunning addition to any aquarium, known for their striking colour morphs, including the beautiful Dwarf Gouramis (Trichogaster lalius). These fish are part of the labyrinth fish family, allowing them to absorb atmospheric oxygen directly. Despite their shy and peaceful nature, these fish require proper care and attention. To ensure their well-being, a well-maintained tank is crucial, as they are susceptible to diseases if water quality is not up to par. It is important to provide a peaceful environment with minimal noise and traffic to avoid making them nervous. When it comes to social behavior, Powder Blue Dwarf Gouramis are generally peaceful towards other fish species. However, males can become territorial and display aggressive behavior during breeding time, especially when kept together in smaller tanks. Batchelor groups of males are often offered, but it is recommended to keep them in odd numbers to avoid bullying. To ensure the best results and avoid aggression, it is suggested to keep more females than males, allowing the smaller, more rounded females to escape excessive harassment should the male decide to court them vigorously. This setup will also allow for the display of natural behavior and help in the formation of breeding pairs. Powder Blue Dwarf Gouramis have an oval-shaped, slightly compressed body, with large, round fins and thread-like ventral fins that contain highly perceptive touch-sensitive cells. Their primary coloration is an iridescent powder blue with minimal vertical red stripes.

How to breed the Powder Blue Dwarf Gourami

Breeding the Powder Blue Dwarf Gourami can be challenging due to unpredictable male behaviour. To ensure successful breeding, a separate breeding tank should be prepared with a low water level, normal water parameters, and slightly raised temperature. The addition of fine-leaf plants like Hornwort or Milfoil and floating plants like Ricca can provide a comfortable environment for the fish. To condition the fish for breeding, a male and one or more females should be fed small portions of frozen and live foods several times a day. Once the females are well-fed and round with eggs, they should be transferred to the breeding tank several days before the male. During spawning, males build a bubble nest and woo the female by raising their dorsal fin and swimming around her. If the female is willing, she will circle with the male and lay her eggs while touching his back or tail. The male then embraces the female and fertilizes the eggs, which float to the top of the water. The male will collect the eggs in his mouth and place them in the bubble nest until anything from 300 to 800 eggs are produced. If there are other females in the tank, the male may breed with all of them. After spawning, females must be removed to prevent attacks from the male. The male will continue to manage and guard the eggs until they hatch in around 12-36 hours. Once the fry become free-swimming, the male should be removed as he may consume the young. Free swimming fry can be fed infusoria or liquid fry food until they are big enough to eat baby brine shrimp.

Diet & feeding

A balanced and diverse diet is crucial to the health and well-being of the Powder Blue Dwarf Gourami. These fish require a combination of meaty and algae-based foods to meet their nutritional needs. While an algae-based flake food can form the foundation of their diet, it should be supplemented with freeze-dried artemia, bloodworm, and tubifex to ensure that their dietary requirements are met. By providing a varied diet, aquarists can promote optimal growth and development, as well as vibrant coloration in these fish.
