L065 (Pseudacanthicus sp., Mustang Cactus Plec, Blizzard Cactus Plec)

A medium-sized catfish with a dark body and covered with yellow-white blotches across the body and fins. Given its size and bulk (and spininess) this catfish tends to uproot and dislodge aquarium plants. On the other hand, it is largely ignored by other fishes of comparable size, so makes a good choice for use in tanks containing large community fishes such as large characins, barbs, catfish, non-aggressive cichlids, etc.


Fish information (behaviour and breeding):

Territorial but otherwise peaceful, this catfish should not be kept with its own species or other catfish of similar shape and size. It will also bully smaller, territorial plecs. An omnivore, this species feeds primarily on small invertebrates such as worms and insect larvae, but will also eat some plant matter. A mix of algae wafers, mussels, prawns, and slice vegetables such as courgette will provide a balanced diet. Some bogwood should also be provided as a source of deitary fibre. No reports of breeding in captivity. Males have more odontodes on the pectoral fins, and females are more robust, but otherwise the two sexes are similar.

Family Group: L Numbers
Distribution Brazil, Rio Tocantins
Temperature 24-28C
Size Up to 20 cm
Water Parameters Adaptable, but avoid extremes
Water PH 6.5-7.5
