Horse Face Loach

About

The horse face loach (Acantopsis choirorhynchos) is named for its distinctively elongated snout and dorsally-placed eyes, giving it a profile unlike almost anything else in the freshwater hobby. Native to rivers and clear, fast-moving streams across Java, Borneo, Sumatra, and the Malay Peninsula, it spends the bulk of its time sifting through sandy substrates in search of small invertebrates and organic matter. In the aquarium, that behavior translates to a fish you set up a display for, then rarely actually see. It burrows, hides, and surfaces largely on its own schedule. A soft, fine sand substrate is really non-negotiable here, both for natural behavior and to protect its delicate snout. Despite a reputation for aggression, most tension stays within the species itself, with occasional squabbles over temporary patches of substrate that seldom result in real injury. Keeping a single specimen or a group of six or more tends to work better than pairs or small trios. Tankmates from the upper water column, rasboras, devarios, and similar schooling fish, generally work well, since they stay out of this loach's territory entirely. One important note: this is a known jumper, so a well-secured lid is not optional. Juveniles are traded regularly, but adults are much less common in the hobby, suggesting their long-term care is often underestimated.
