Leporacanthicus galaxias
Galaxy Plec, L029
Classification
Loricariidae, Subfamily: Ancistrinae
Distribution
Various river basins in Brazil, including the Amazon and Tocantins.
Habitat
A reophilic species that lives in rapids and other fast-flowing waters.
Maximum Standard Length
10″ (25cm).
Aquarium SizeTop ↑
It is territorial, so a tank measuring at least 48″ x 18″ x 18″ (120cm x 45cm x 45cm) – 243 litres is required to house one properly.
Maintenance
A spacious tank is required, preferably with a sandy substrate. Provide hiding places and shade with some big chunks of driftwood and smooth rocks. Dim lighting is also beneficial and it’s imperative that the water is highly oxygenated, preferably with a good amount of movement. Consider the use of powerheads or large airstones to produce the desired effect. An efficient filter is needed to deal with the large amounts of waste it produces.
Water Conditions
Temperature: 72-79°F (22-26°C)
pH: 5.6-7.0
Hardness: 0-10°H
Diet
Not a particularly vegetarian Loricariid, L. galaxias will accept most sinking dried foods, and also enjoys munching on meatier fare such as earthworms, prawns, mussels, bloodworm and suchlike. Oddly for a Loricariid, it also relishes snails.
Behaviour and CompatibilityTop ↑
Generally peaceful with species inhabiting other parts of the tank. In a biotope setup good tankmates include larger characins such as Anostomus, Hemiodus, Semaprochilodus and Metynnis species, reophilic cichlids such as Retroculus and in a big tank, other Loricariids requiring similar conditions.
It’s territorial towards other benthic species, particularly those with similar colour patterns. A group would need very roomy quarters.
Sexual Dimorphism
When viewed from above mature males have a noticeably longer and wider head than females. They also have a bigger dorsal fin and more numerous odontotes than females.
Reproduction
Has been bred in the hobby, but no details are available. It spawns in deep holes in river banks during the wet season in nature.
NotesTop ↑
A very stylish looking plec, L. galaxias can also be seen for sale as the vampire or tusken plec. Both these names relate to features of morphology that are shared by all members of the genus. The latter arose from the presence of a characteristic growth on the head of the fish. The vampire moniker, meanwhile, is derived from the unique upper jaw dentition, consisting of, you guessed it, two large teeth or “fangs”. The exact use for these is unknown, but they’re probably utilised to grip prey items such as snails or other aquatic invertebrates in some way.
There are four similar but undescribed variants of this species available, which may turn out to be geographical forms or species in their own right. They are all known as Leporacanthicus cf. galaxias and so are best referred to by their L numbers. The first, L007 is imported from Brazil and has a pattern consisting of larger spots than the true L. galaxias. It also has a shorter nose and bigger dorsal fin than galaxias. Both L240 and L241 are Venezuelan in origin. L240 is very difficult to tell apart from galaxias and may turn out to be the same fish, while L241 has a more flattened profile when viewed side on. The fourth variant, L294 is also from Brazil, but very little other information is available and we’ve never seen one in the flesh.
A final point to note. When buying these (or any Loricariid), check the fish has a rounded belly and that its eyes aren’t sunken, as these are classic signs of emaciation in newly imported specimens.
