Overview

The Colombian Shark Catfish has a silvery body, tall dorsal fin and an active swimming style. Despite often being sold small, it is a specialist estuarine fish with substantial adult requirements.

English name Colombian Shark Catfish
Latin name Ariopsis seemanni
Origin Pacific coastal rivers and estuaries of Central and northwestern South America
Adult size Around 35 cm, potentially larger
Typical lifespan 10 years or more
Temperament Predatory towards smaller animals
Tank level Middle and lower
Social needs Social species; plan a suitably sized group and full adult housing before purchase.

Tank Setup

Aquarium size Specialist adult aquarium of at least 600 litres with a 180 × 60 cm base; a social group requires considerably more space.
Temperature 24-28°C
pH 7.5-8.5
Hardness Hard, mineral-rich water; adult salinity must be planned separately from GH.
Water type Specialist brackish to marine adult setup

Adults need brackish to marine conditions, ample swimming space, strong filtration and high oxygen levels. Agree the current salinity and any gradual transition with our aquatic team; use marine salt and measure salinity accurately.

Behaviour & Compatibility

Will swallow small tankmates. Choose robust companions suited to the same adult salinity and space requirements; this is not a permanent freshwater community fish.

Diet & Feeding

Offer sinking carnivore pellets and suitable marine invertebrate foods. Avoid mammal meat and routine feeding of live fish.

Routine Care

Use a fully cycled aquarium before adding livestock. Check temperature, appetite and behaviour daily. Test water regularly: ammonia and nitrite must remain at zero. Make regular partial water changes with conditioned water matched to the aquarium's temperature and chemistry. Keep nitrate low and rinse biological filter media in removed aquarium water.

Check salinity as well as water quality. Replace evaporated water with fresh water, since salt remains behind; match the salinity of water removed during changes.

Click & Collect Only

You can order online for Click & Collect. We will confirm when your livestock is ready to collect from Newlands Home and Garden Centre, Clondalkin, Dublin 22. We do not deliver live fish or aquatic invertebrates. Please have a suitable, fully prepared aquarium ready before collection.
