Pangasius nasutus (Long-Nosed Pangasius) Care Guide Summary

The Pangasius nasutus (Long-Nosed Pangasius), scientifically known as Pangasius nasutus, belongs to the Catfish family group. Adults reach a maximum size of approximately 90 cm and have a fusiform body shape with a fast growth rate. Classified as mostly peaceful, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a extreme level of biological waste.

To thrive, the Pangasius nasutus (Long-Nosed Pangasius) requires a freshwater only aquarium with a minimum volume of 4000 litres and a tank length of at least 300 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6.57.5 and a general hardness of 515 dGH. A moderate water flow is preferred.

The Pangasius nasutus (Long-Nosed Pangasius) is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Adult (Standard) and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Pangasius nasutus (Long-Nosed Pangasius) Habitat Setup

When setting up an aquarium for the Pangasius nasutus (Long-Nosed Pangasius), a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper.

Pangasius nasutus (Long-Nosed Pangasius) Compatibility Notes

Classified as mostly peaceful, the Pangasius nasutus (Long-Nosed Pangasius) is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, shy or slow-feeding tankmates may be outcompeted at feeding time, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Pangasius nasutus (Long-Nosed Pangasius) Feeding & Diet Considerations

The Pangasius nasutus (Long-Nosed Pangasius) is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided and is an aggressive eater that may prevent timid tankmates from getting enough food, so target feeding or simultaneous feeding at opposite ends of the tank can help.
