Tatia perugiae 1 - 2, (Tatia perugiae) — 1-2,5cm

Overview

For aquarists seeking a tropical fish UK specialist offering rare micro-species, Tatia perugiae is a small, peaceful nocturnal catfish native to the Amazon Basin, especially Peru and adjacent parts of western South America. This diminutive driftwood catfish rarely exceeds 2.5 cm in captivity, making it one of the smallest catfish available in the hobby. Its shy nature and fascinating hidden behavior make it ideal for a quiet planted aquarium housing other peaceful nano species. At Tropical Fish Co, we supply healthy juveniles that adapt well to soft-water setups and reward attentive care with years of engaging, secretive behavior.

Appearance and Coloration

Tatia perugiae displays a mottled brown and cream base color with irregular dark blotching across the body. The patterning provides excellent camouflage against driftwood and leaf litter. The body is elongated and slightly compressed, with a broad head, prominent eyes, and short barbels. The fins are semi-translucent with faint pigmentation, and the adipose fin is well developed. Under subdued lighting, the mottled pattern blends seamlessly with natural décor. Juveniles at 1–2.5 cm show the same cryptic coloration as adults, helping them avoid predation in the wild.

Natural Habitat and Distribution

This species inhabits slow-moving tributaries, flooded forest zones, and leaf-litter-rich streams of the Amazon Basin. Water conditions are typically warm (24–27 °C), soft, acidic, and heavily tannin-stained. Tatia perugiae is primarily nocturnal, hiding among submerged logs, root tangles, and dense vegetation during the day. At dusk, it emerges to forage for small invertebrates and organic debris. The substrate is fine sand or mud, and the environment is dimly lit with minimal current. Replicating these blackwater conditions at home encourages natural behavior and optimal health.

Aquarium Setup and Décor

A 40-litre aquarium is suitable for a small group of five to seven Tatia perugiae. Use soft sand or very smooth substrate, and provide plenty of driftwood, leaf litter, and caves. Live plants such as Java fern, Anubias, and Cryptocoryne are ideal. Floating plants help diffuse lighting and create shaded zones essential for this shy species. Subdued lighting is critical to reduce stress and encourage the catfish to emerge during evening hours. Avoid bright tanks, strong currents, and coarse substrates. A secure lid is recommended, as these fish are strong swimmers and may explore surface areas at night.

Feeding and Nutrition

Tatia perugiae is primarily carnivorous. Offer appropriately sized sinking carnivore foods, frozen or live foods such as bloodworms (chopped if necessary), blackworms, brine shrimp, daphnia, and small insect larvae. Feed once daily in the evening after lights out, as this species is primarily nocturnal. Ensure food reaches the substrate and is not consumed entirely by faster mid-water fish. Use sinking micro-pellets designed for small carnivores as a staple. Avoid large pellets or flakes, which this tiny species cannot consume.

Behaviour and Social Structure

These catfish are highly secretive and primarily nocturnal. During the day they remain hidden among driftwood, leaf litter, and dense vegetation. At dusk they emerge to forage, moving slowly across the substrate in search of micro-invertebrates. Tatia perugiae is peaceful and can be kept in small groups, which provide security and encourage more confident behavior. In a well-planted aquarium with subdued lighting, they may occasionally be visible during late afternoon hours. Avoid strong competition at feeding time, as this species is a slow, deliberate feeder.

Compatible Tank Mates

Ideal companions include small peaceful community fish such as micro-rasboras (chili, Phoenix), nano tetras (ember, green neon), and dwarf Corydoras (pygmaeus, hastatus). Non-aggressive tetras, rasboras, and dwarf cichlids that do not harass bottom fish are also suitable. Avoid housing with large predatory fish, aggressive cichlids, fin-nippers, very boisterous bottom-dwellers, or species that outcompete them for food. Small shrimp can coexist if the tank is well planted and offers hiding spaces.

Breeding in the Aquarium

Breeding is uncommon in home aquaria. Like other driftwood catfish, it is likely a cavity spawner; provide secluded hiding places, stable warm water, and a protein-rich diet, but successful spawning is rarely reported. Sexual dimorphism is subtle; females may be slightly plumper when carrying eggs. If breeding is attempted, provide small caves or PVC tubes and monitor water parameters closely. Fry, if produced, require specialized care and micro-foods such as infusoria or liquid fry food initially.
