Overview
The mango loach is a true nano stone loach, small and peaceful enough for a mature little tank. It suits a keeper who has kept fish before.
Did you know
The mango loach really is named for the fruit. Its describers borrowed the fruit's name for the warm orange-red of mature males, a rare case of taxonomy simply saying what it saw.
Caring for the mango loach
Keep a small group of mango loaches in a mature, well-established tank of 11 gal (40 L) or more. Give them fine sand, smooth pebbles and a few plants for cover. They perch on pebbles and hop between stations along the bottom rather than swimming in open water.
Keep the water cool to middling, at 68 to 77°F (20 to 25°C) and a pH of 6.5 to 7.8. Filter gently, for soft flow rather than a torrent. Stable, clean, well-aged water matters, since a loach this tiny has little tolerance for swings.
Feed the finest foods, such as baby brine shrimp, crushed flake and micro sinking granules. The mango loach is peaceful, so keep it with tiny tank mates such as microrasboras or small danios. Mature males show a bright orange-reddish body crossed by a dark stripe. Its aquarium breeding has not been recorded.
Good to know
Physoschistura mango is one of the smallest known stone loaches. Kevin Conway and Maurice Kottelat described it in 2023, and it belongs to the family Nemacheilidae.
In the wild
The mango loach comes from clear, gentle waters of Shan State in Myanmar. It is a small fish from small habitats.
