Description
The galaxy plec (L029), also sold as the vampire or tusken plec, is a loricariid of about 25 cm from the rapids and fast-flowing waters of several Brazilian basins, including the Amazon and Tocantins. It has an unmistakable look, with pale spots on a dark ground and long teeth.
Four similar undescribed variants, L007, L240, L241 and L294, are better called by their numbers. It is territorial: it needs a tank of at least 120 cm.
Behavior
Generally peaceful with fish from other parts of the tank, but territorial towards other bottom catfish, especially those with a similar pattern.
It lives well with large open-water characins and, in very large tanks, other rapids loricariids.
Avoid housing it with other bottom fish of similar appearance; a group needs an enormous tank.
Habitat
Leporacanthicus galaxias is a reophilic species of rapids and fast-flowing water in several Brazilian basins.
In the aquarium it asks for strong current, plenty of oxygen, rocks and caves, and a long tank.

Water: FishBase gives pH 6.2-7.2 and 22-25 °C; Seriously Fish, pH 5.6-7 and 22-26 °C. The profile uses the widest range. Hardness, 0-10 dGH, comes from Seriously Fish: FishBase does not record it. Size: 21.1 cm SL in FishBase and 25 cm SL in Seriously Fish; the larger is taken.
Litres per fish and minimum tank height and depth: the profile's own judgement. Seriously Fish gives only the tank base and FishBase gives no tank sizes.
