Check the scientific name when buying, as common names vary between sellers and countries.
Females are larger and rounder, and they look broader when viewed from above.

Use a soft sand bottom, because rough gravel can wear down its barbels, and keep the water clean. It sometimes darts to the surface for air, which is normal.
Behaviour and Tankmates
A peaceful, sociable bottom-dweller that spends the day rooting through the sand in a group.
Keep a group of at least 6, and more if you can.
Not territorial.
An ideal community fish, with small, peaceful fish that like similar water. It does not eat algae or clean the tank, so it needs its own food.
Water Parameters
Fairly tolerant of different water, if it is clean and stable. Keep the temperature steady.
Parameter caveat
Keep up regular water changes, and acclimatise new fish slowly.
