Water temperature 21oC, current velocity 10l/sec. The stygobitic loricariid Ancistrus galani inhabits a nearby system. Various other stygobitic and stygophilic species are also present. See Rodriguez and Bosque (1990) for further details.

Systematics

There is little information on the relationships of this species. DoNascimiento, Villarreal and Provenzano (2001) compare its anatomy with various other Trichomycterus species but without conclusive results.
