Golden Zebra Loach Botia histrionica
Oftentimes, the common names of the species we keep in aquariums appear almost to have been chosen at random, but the Golden Zebra Loach is a fish that has been perfectly named. The base coloration of its body is golden in tone (albeit a bit dull compared to that of a Gold Barb), and adorning the sides of adults are a series of black stripes which do indeed give one the impression of a zebra.
What’s more, the appearance of this fish changes quite dramatically as it matures. Juveniles (which are typically how one comes across this species in the aquarium trade) sport several thick black bars. But, upon reaching its adult dimensions of nearly 6 inches, these markings fracture into many smaller, thinner, more-convoluted lines and stripes. Additional spots can also develop between the original bars, creating a dense array that can appear more like a tiger than a zebra. But, whichever carnivorous analogy one prefers, this fish is a stunner all the same.
Botia histrionica originates from across a large swath of Southeast Asia, from India to Myanmar, in association with the Ayeyarwaddy River and other nearby drainages. What little is known of this fish in the wild indicates it occupies well-oxygenated headwaters whose substrate consists of sand and gravel. Here it travels about in large shoals which feature a complex hierarchy. This is of concern for those wishing to keep this species in captivity. As with most loaches, a modestly sized group is recommended, numbering perhaps a half-dozen or more. Too few can lead to issues of territoriality and dominance among rivals, so always err on the side of keeping more individuals. In larger systems, a shoal of ten or twenty specimens can make for a mesmerizing sight.
A carnivorous diet of sinking pellets and frozen worms and shrimp will keep the Golden Zebra Loach in good health. This fish can be mixed with other bottom-dwellers, like freshwater sharks, Garra, catfishes and even other loaches. To be avoided are tankmates in possession of long, trailing finnage, such as bettas or angelfishes, while some good choices for a Southeast Asian biotope might include gouramis, barbs, and glassfishes.
