Did you know
The Chinese spiny loach carries a spine under each eye that folds flat in a groove. This spine gives the spined loaches their name. It flicks the spine out when threatened, like a hidden pocketknife.
Caring for the Chinese spiny loach
Give the Chinese spiny loach a tank of 42 gal (160 L) or more, with a sand floor and gentle flow. It sifts mouthfuls of sand all day and takes no interest in anything above the floor.
Keep the water cool, at 59 to 75°F (15 to 24°C), with a pH of 6.5 to 7.5. Feed sinking granules and frozen foods.
The Chinese spiny loach is easygoing and peaceful with everything, and it does fine alone or in a group. Keep it with other coolwater fish, such as white clouds, minnows or hillstream species.
