Relevant Information:

Occurs in principal river beds, in upstream parts of rivers, downstream rapids, in backwater zones or on stony bottoms of pools with dead tree trunks. Active at dusk. Piscivorous. Emits loud grumblings. Secretes toxic mucus and the wounds caused by its pectoral spines are very painful. The female can preserve spermatozoids by coating them with original maternal secretions and inserting them in the epithelium of its genital tract. The presence of sperm in the mucus of the female's genital tract is indicative of internal  fertilization. Aquarium Care: Can be predatory with smaller tankmates so choose carefully. Not suited to be housed with smaller species but should fit in with South American Cichlids, L-number cats and members of the Doradidae family. Diet: Gregarious feeders in the aquarium and are not fussy eaters. Earthworms, white and black worms, Tilapia filets, or trout pieces, tablet and pellet foods and frozen foods such as bloodworm. When adult you do not need to feed this fish every day, every second day would suffice on the diet of the above foods.
