Galaxias Dwarf 2cm

Galaxias Dwarf

Galaxiella Pusilla, also known as the dwarf Galaxia, is a freshwater fish species that are native to the southern regions of Australia and is hardly ever seen in the aquarium hobby. Galaxias are a really underrated family of native Australian fish which are very adaptable to a range of conditions. For aquarists chasing a simple species-only aquarium or a unique fish to add to a cold water community tank, this will be a great consideration. 

The Galaxiella Pusilla has a slender and elongated body, with a light brown to olive-green body coloration. Galaxias is a scaleless fish and has a skin instead which has a stunning metallic sheen.  The green body colour is broken by a series of horizontal lines that travel from head to tail. The underbelly contrasts this with a creamy white which really just highlights the simplicity of this fish. Some other notable features include this fish's rounded snout and comically large eyes, which give it a unique appearance. These fish only reach around 6 cm and have a lifespan of around 5 years in captivity.

Breeding the Galaxiella pusilla is relatively straightforward as they are egg scatterers. It is difficult to sex these fish visually as they have no distinguishable external differences between males and females. However, breeding can be stimulated through a gradual temperature increase and the use of spawning mops. The eggs will hatch within 7 to 10 days, and the fry can be fed with infusoria or small fry foods.

Tank Recommendations for your Galaxiella Pusilla

Since these fish only reach around 6 cm, a school of 5-6 only needs an aquarium of 70 litres however a larger tank will be better. Through these fish are hardy, they can be slightly sensitive to drastic parameter swings, It is essential to maintain stable water parameters with a pH between 6.5-7.5 and a temperature of 20° Celsius. A planted tank with river stones, driftwood, and hiding places is recommended since these fish can be slightly skittish. Having a tight-fitting lid is also a must because these dwarf galaxias will jump.  

Suitable Tank Buddies

The Galaxiella pusilla is a peaceful fish and can be kept with other small, peaceful cold water fish species.

Usually Compatible

Pygmy perch, glass fish, other Galaxia species, hillstream loaches, danios, and other cold-water nano species.

Sometimes Compatible

Cold water-tolerant barbs can be considered however there is a risk that these fish can nip the fins of the galaxies. The range of species that can be kept is quite minimal due to the temperature requirements.

Rarely Compatible

Larger and more aggressive fish species such as Oscars and peacock cichlids should not be kept with the Galaxiella pusilla due to the risk of predation. Tropical species should also be avoided. 

Feeding your Galaxiella Pusilla

In the wild, the Galaxiella pusilla feeds mainly on small invertebrates and micro-crustaceans. In captivity, they can be fed a varied diet consisting of high-quality flakes, pellets, and frozen or live foods such as bloodworms and brine shrimp. These fish are not fussy eaters and will readily accept most types of food. It is best to feed small amounts two to three times a day.
