Breeding Mystus vittatus

Breeding notes for Mystus vittatus, the striped dwarf catfish: an oviparous South Asian bagrid that produces sounds during spawning; aquarium spawning is undocumented.

Overview

Mystus vittatus, the striped dwarf catfish, is a bagrid of the family Bagridae reaching about 21 cm. FishBase records it across the Indian subcontinent and parts of Southeast Asia. It is usually found among marginal vegetation in lakes and swamps with a mud substrate, in both standing and flowing waters, and is capable of facultative air-breathing. The species is listed as Least Concern by the IUCN.

Sexing

FishBase gives length at first maturity at around 9 cm standard length. Reliable external sexing characters are not documented for this species in the consulted sources.

Spawning Behavior & Trigger

FishBase classifies the species as oviparous, with distinct pairing possibly like other members of the family. A notable detail reported on Wikipedia is that these catfish are known to make sounds during spawning. Detailed spawning conditions, fecundity and egg data are not documented.

Common Challenges

Because there is no published aquarium spawning account and only fragmentary natural-history data, reproduction cannot be planned around a verified method.
