Breeding Glyptothorax trilineatus

Breeding notes for Glyptothorax trilineatus, a hillstream sisorid catfish of cool mountain rapids: reproduction is undocumented and no aquarium spawning is recorded.

Overview

Glyptothorax trilineatus is a hillstream catfish of the family Sisoridae, reaching about 30 cm total length. FishBase records it from India, Myanmar, Nepal, Thailand and Laos, with reports from China, and notes it occurs in basin-wide tributaries of the lower Mekong. It inhabits pool and riffle areas of fast, rapid-running mountain streams. FishBase lists a temperature range of 10-20 degrees Celsius, pH 6.0-7.2 and hardness up to 10 dH, reflecting cool, oxygen-rich hill-stream conditions.

Common Challenges

Two factors stand out. First, no maturity, spawning, fecundity or egg data exist in the consulted source, so there is no reproductive baseline to work from. Second, the species requires cool, strongly oxygenated, fast-flowing water, which is difficult to reproduce and sustain in a home aquarium.
