Malabar Baril
Barilius bakeri
Also known as: Blue-spotted Hill Trout
A fast, bold stream fish that needs equally confident tankmates to thrive.

About
The Malabar Baril (Barilius bakeri) is a lively cyprinid native to the cool, clear mountain streams of the Western Ghats in Kerala, India. A region known for its fast-flowing, well-oxygenated waters. In the aquarium it carries a row of bluish-green spots running along each flank, white-edged dorsal and anal fins, and a streamlined build that hints at just how quickly this fish can move. Worth noting is that those spots are most vivid in younger fish and tend to shrink and fade with age. This species goes by a handful of trade names including 'royal danio' and 'blue-spotted hill trout', so you may encounter it under different labels. Despite being listed as beginner-friendly in terms of basic care, the Malabar Baril is not a straightforward community fish. It is a seriously fast swimmer and an aggressive feeder that can easily outcompete slower, more timid species at mealtimes, and small fish risk being eaten outright. The best companions are robust, similarly-sized pelagic cyprinids, along with bottom-dwellers like Garra or Botia that stay out of its way. Keep a group of at least five. Fewer than that and the weaker individuals tend to take a real beating from dominant fish. Given a suitable group and the right tankmates, it settles in well and makes an active, rewarding display fish.
