Breeding Peckoltia snethlageae (L141)

Breeding the L141 Peckoltia snethlageae: sexing by body odontodes, a cave setup and male brood care following the documented Peckoltia pattern.

Overview

Peckoltia snethlageae, traded as L141 (also L215) and known as the ghost pleco, occurs in the Tapajos basin in Brazil. Wikipedia notes the species, originally described by Steindachner in 1911, has been reclassified across several genera and placed in Ancistomus in a 2015 review; it reaches about 22 cm total length and is listed as Endangered by the IUCN. Species-specific spawning reports are scarce, so the account below follows the documented breeding biology of the genus Peckoltia.

Sexing

In Peckoltia, most males develop hypertrophied body odontodes during the breeding season, which is the principal external sign of sex; males are also usually more slender than ripe females.

Breeding Setup

Because these catfishes hide in cavities in submerged logs and rocky riffles, the breeding tank should offer enclosed caves sized to the adults. Well-oxygenated water with movement reflects their riffle habitat.

Spawning Behavior & Trigger

As cave spawners, the female deposits a clutch inside a cave and the male is responsible for tending and guarding it, in line with the documented Peckoltia pattern.

Egg & Fry Care

Following the genus pattern, the male guards the clutch in the cave through hatching, and the fry remain in or near the cave until their yolk reserves are used up before becoming free-swimming.

Common Challenges

As a comparatively large, semi-territorial Peckoltia, this species needs spacious caves and ample cover so a breeding male can hold a territory without persistent conflict. Its Endangered IUCN status makes captive-bred stock especially valuable.
