Food

Algae wafers, blanched vegetables (courgette, cucumber), and driftwood to rasp; add some frozen or sinking protein.

Tap a food to see what it is.

Male or female

Seen from above, mature males have a noticeably longer and wider head, a bigger dorsal fin and more odontodes than females.

Health

Breeding

Cave spawner ·

Has been bred in the hobby but no details are published; in nature it spawns in deep holes in river banks in the wet season.

Pairing

Grow out 6-8 juveniles and let a pair form; keep the group in a well-oxygenated, stable tank.

Setup

100-200 L tank with strong flow, many caves sized to the fish (PVC or ceramic tubes), and very clean, warm water.

What starts it

Cool water changes, increased flow and a seasonal drop in temperature, plus rich protein feeding.

Eggs

The male guards a small clutch (5-30 large amber eggs) in the cave for around 5-10 days until they hatch; the fry carry a big yolk sac.

Raising the fry

Fry stay in the cave until the yolk is gone, then feed on sinking algae wafers, blanched veg and crushed flake. Keep nitrate low.

Common mistakes
  • Too few caves
  • Warm, stagnant water
  • Moving the male while he guards eggs

The story of the vampire pleco

Named 'vampire' for the two large fang-like teeth in the upper jaw shared by all Leporacanthicus, and 'tusken' for the bony growth on its head. A rapids-dwelling fish from Brazil, it eats meaty foods and, unusually for a pleco, relishes snails.

Isaäc Isbrücker and Han Nijssen described this pleco in 1989. Its long, fang-like teeth gave the whole genus the name 'vampire plecos'. It is known as the galaxy pleco because of the white spots on its dark body.

First described by Isaäc J. H. Isbrücker & Han Nijssen in 1989. Named for 'galaxias' refers to its star-like white spots.

  • Its long front teeth help it pick snails and other prey from crevices.
  • It is often called the galaxy pleco.
  • It is mainly carnivorous and needs meaty foods.

  • Scientific name

    Name valid, but legacy L-number is WRONG: L. galaxias is L029, not L340 (L340 is a Hypancistrus, the 'mega clown pleco'). L007, L240, L241 and L294 are similar undescribed L. cf. galaxias; fish sold as 'vampire pleco' may be any of these. Fix the display name and aka.

  • Group sizeSeriously Fish: Leporacanthicus galaxias (galaxy plec, L029)
  • Temperamentcorrected

    Legacy 'semi-aggressive'. SF rates it peaceful toward fish in other zones but territorial with bottom-dwellers. Will eat snails.

  • Care levelcorrected

    Legacy care 3 (hard). SF rates it easy but stresses a large tank, strong current and high oxygen; 'moderate' would be a fair site choice.

    Legacy 'predatory pleco' overstated: it eats invertebrates and meaty foods, not fish. Spot pattern not described in words by SF; SF only notes L007 has larger spots than true galaxias.
