Atipa, Hoplo Cat, Bubblenes — Atipa Hoplo Cat Bubblenes (Hoplosternum thoracatum) 6.5-8 cm

Overview

The Atipa, also known as the Hoplo Cat or Bubblenes, is Hoplosternum thoracatum, a hardy and characterful South American catfish prized for its peaceful nature and excellent adaptability. Offered at a size of 6.5-8 cm, these juveniles make a superb choice for aquarists looking for a robust bottom-dweller that can settle into a wide range of community aquariums.

This species is well known for its armour-plated body, whisker-like barbels and calm temperament. Unlike many catfish, the Hoplo Cat is active in a gentle, unhurried way and is often seen exploring the substrate, resting under décor, or coming out at feeding time. It is a great option for hobbyists who want a fish with personality without the aggression or specialist demands of more delicate species.

At Tropical Fish Co, we supply healthy livestock with fast UK delivery and a live arrival guarantee, so your new fish arrives in the best possible condition. With sensible aquarium care, Hoplo Cats can become long-lived, engaging residents that add real interest to the lower levels of the tank.

Care at a Glance

Origin & Natural Habitat

Hoplosternum thoracatum is native to tropical South America, where it inhabits slow-moving rivers, floodplains, marshes and seasonally inundated waters. In the wild, it is adapted to environments that can vary in oxygen levels, water depth and flow, which helps explain why it is such a resilient aquarium fish.

These habitats often contain soft substrates, leaf litter, submerged roots and dense marginal vegetation. The Hoplo Cat uses its barbels to search for food among the bottom detritus and plant debris. It is also capable of gulping air at the surface when needed, a useful adaptation in low-oxygen waters. This natural hardiness makes the species especially suitable for community aquariums, provided it is kept in clean, well-maintained water.

Tank Setup & Water Parameters

Although the Atipa is tough, it still benefits from a thoughtfully arranged aquarium. A spacious tank with plenty of floor area is ideal, as this species spends most of its time near the substrate. We recommend a minimum of 200 litres for a single adult or a small group, with extra room if you plan to keep it with other bottom-dwelling fish.

Use a soft sand or very fine gravel substrate to protect the barbels and underside of the fish. Sharp gravel can cause abrasion and should be avoided. Add driftwood, smooth rocks, caves and shaded areas to create cover and reduce stress. Live plants are welcome, though the fish is not usually destructive; sturdy species such as Java fern, Anubias and Cryptocoryne work particularly well.

Gentle filtration and moderate water movement are ideal. While Hoplo Cats tolerate a broad range of conditions, they do best in stable water with regular maintenance. Aim for:

• Temperature: 18-28°C
• pH: 5.5-7.8
• Hardness: 0-20 dGH

Weekly partial water changes are strongly recommended to keep nitrate low and maintain excellent water quality. Good oxygenation is beneficial, especially in warmer aquariums. A secure lid is also sensible, as active catfish may occasionally dash to the surface.

Feeding Guide

The Hoplo Cat is an omnivore with a healthy appetite and a varied diet. In the aquarium it will readily accept sinking catfish pellets, wafers, frozen foods and quality prepared foods. To keep it in top condition, offer a mix of:

• Sinking carnivore or omnivore pellets
• Algae wafers and bottom feeder tablets
• Frozen bloodworm, daphnia and chopped mysis
• Occasional live foods where appropriate
• Small amounts of blanched vegetable matter

Feed once or twice daily in portions the fish can consume within a few minutes. Because Hoplo Cats are active after lights dim, it can be helpful to offer some food in the evening so they are not outcompeted by faster tank mates. A varied diet supports strong growth, vibrant condition and long-term health.

Tank Mates / Compatibility

Hoplosternum thoracatum is generally peaceful and makes an excellent community fish. It is best kept with calm to moderately active species that will not nip fins or harass it at feeding time. Good companions include tetras, rasboras, peaceful barbs, rainbowfish, gouramis, livebearers, dwarf cichlids and other non-aggressive catfish.

Because this species grows to a substantial size, avoid pairing it with very small fish that could be intimidated, or with highly territorial bottom dwellers that may compete for the same space. It is usually fine with other peaceful catfish if the tank is large enough and has plenty of hiding places.

As with many catfish, avoid keeping it with aggressive cichlids, fin-nippers and species that demand very warm, highly specialised conditions. A well-planned community aquarium will allow the Hoplo Cat to display its natural behaviour and thrive for years.
