Overview
This sand-loving whiptail is social and peaceful, so keep a small group over a wide open floor of fine sand, which it burrows into until only its eyes show. It sifts sand and grazes biofilm and small foods, so offer sinking pellets, wafers, and frozen items such as bloodworm, and make sure enough reaches the bottom. Keep it with calm, gentle tankmates that will not compete at the floor. Plan on at least 250 liters with a wide sand bed, driftwood, and shaded hides.
In the wild
It is widespread across the lowlands of the Amazon and Orinoco, lying on soft sand in calm and slow-flowing reaches. Above all it needs a wide, open bed of fine sand, along with driftwood and a few shaded caves. Keep the water warm at about 24 to 28 C with a pH of 6.0 to 7.4, soft and slightly acidic to neutral, and gentle in flow.
Good to know
Loricaria simillima is a loricariid that reaches about 26 centimeters, a slim, flattened whiptail marbled to blend with sand. It is a paternal lip-brooder: after spawning, the male carries the mass of eggs tucked against his enlarged lower lip and barbels for roughly two weeks. Breeding is of moderate difficulty.
Did you know
The male is the one that carries the eggs. He holds the whole clutch bundled against his lower lip and barbels for about two weeks, even burying into the sand with the eggs still attached, and cleans them several times a day.
