Can Angelicus Pleco L073 and Giant Whiptail Catfish Live Together?

Angelicus Pleco L073 is a generally mild-mannered species (3/10), while Giant Whiptail Catfish is peaceful (2/10). This modest difference means Angelicus Pleco L073 may occasionally assert dominance over Giant Whiptail Catfish.

Angelicus Pleco L073 and Giant Whiptail Catfish both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Worth noting: Angelicus Pleco L073 is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

There is no temperature overlap between Angelicus Pleco L073 (26–30°C) and Giant Whiptail Catfish (16–23°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–15 dGH. Regular testing will ensure conditions stay within this range.

To house Angelicus Pleco L073 and Giant Whiptail Catfish together, plan for an aquarium of at least 400 litres with a minimum length of 150 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Sand (Sifters), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.
