Crying Whiptail Care Guide - Aquarium Setup, Diet & Breeding

The Crying Whiptail is an elegant, elongated loricariid with a slender body, a long tapering tail and a broad, flattened head. Its earthy brown coloration and fine markings provide effective camouflage among leaf litter, sand and submerged branches. The name is commonly linked to the dark, tear-like markings around the eyes seen in this form.

This is a peaceful, largely nocturnal catfish that spends much of its time resting on the substrate or clinging to wood and other solid surfaces. It moves deliberately rather than darting around the aquarium, using its sucker-shaped mouth to examine surfaces for food.

In the wild, Crying Whiptails inhabit quiet margins and slower-flowing rainforest waters in the Río Atabapo system. These habitats are often rich in submerged roots, branches and decomposing plant material, with subdued light and naturally low mineral content.

Although it is generally undemanding in temperament, this whiptail is a specialist-looking fish that benefits from a mature aquarium with established surfaces to explore. Individual fish may be shy when first introduced, but they often become more visible once settled, particularly during the evening and after lights out.

Loricaria sp. 'rio atabapo' originates from the Río Atabapo region of the upper Orinoco basin in northern South America, associated with Colombia and Venezuela. It comes from warm, soft, generally acidic rainforest waters with sandy or silty areas and submerged wood.

A single Crying Whiptail should have at least 120 litres, with a footprint of roughly 120 by 40 cm; a larger aquarium is preferable for several adults. Use fine sand or another smooth substrate to protect the underside and mouth, and provide substantial driftwood, roots, broad shelters and narrow spawning caves. Moderate flow, shaded areas, hardy plants and excellent oxygenation recreate the structure of its rainforest habitat while leaving open bottom space for foraging.

Up to around 15 cm (6 in) in total length. Females may become slightly deeper-bodied, while mature males can appear more robust around the head and develop stronger odontodes.

Offer a varied diet centred on sinking algae wafers, spirulina-based foods and soft vegetables such as courgette, cucumber, spinach and shelled peas. They also benefit from occasional meaty foods including sinking tablets, bloodworm, daphnia or other small frozen foods, especially when conditioning them for breeding. Feed after dark or near dusk so they are not outcompeted, and do not rely on naturally occurring algae alone.

Crying Whiptails are peaceful and suitable for a calm community aquarium. Good companions include small tetras, pencilfish, peaceful rasboras, dwarf corydoras, small non-aggressive South American cichlids and gentle livebearers that appreciate similar conditions. Avoid boisterous feeders, fin-nipping species, large predatory fish and aggressive territorial bottom dwellers, which may outcompete, injure or repeatedly disturb them.

Crying Whiptails are cave-spawning catfish. Provide a clean, narrow spawning tube or suitably sized cave, along with excellent water quality and a varied, nutritious diet. The male usually guards the adhesive egg mass inside the shelter, fanning it with his fins until the eggs hatch. Fry can be raised on very small foods, algae-based foods and finely prepared sinking diets once they become free-swimming.

Mature males are usually slimmer and may develop fine bristles or odontodes on the head and along the pectoral-fin region, particularly when ready to breed. Females are generally broader through the abdomen, especially when carrying eggs, and usually have a smoother head.
