General Description: The Ripsaw Catfish, also known as the Niger Catfish, is found widely throughout main river channels of the Amazonian biotope in northern South America. Often sold as juveniles or subadults, this catfish species is truly a river monster that is best left admired in the wild, public aquaria or to the few extremely dedicated aquarists that have the facilities to house an adult Ripsaw catfish. On average, an adult Ripsaw catfish can grow up to 3 feet in length. While a Ripsaw catfish is not likely to obtain this size in captivity, it will still grow much too large for the majority of hobbyists making this fish a serious commitment in all aspects of aquatic husbandry (please see ‘Diet and Care Requirements’ below). For its enormous adult size however, the Ripsaw catfish is quite the gentle giant. The Ripsaw catfish is aptly named for the large spines it develops as an adult that run down the lateral line of the fish.

Diet Requirements: Ripsaw catfish are omnivorous detritivores, meaning that they will consume just about anything that falls to the substrate. Offer options such as frozen brine shrimp, mussels, krill, and prawns. Foods containing Spirulina algae are a plus. Appropriate frozen food options will vary depending on the size of your specimen. Ripsaw catfish may accept large sinking pellet foods, but these should not make up the majority of their diet. Live earthworms are a favorite treat. Variety is the spice of life in order to maintain color, immune function and longevity of your fish. Ripsaw catfish are notorious for becoming greedy and will often learn to “beg” for food, but feeding only once a day should be exercised for juveniles. Adult specimens may only need to be fed once a week. Obesity is a big problem in large catfish species, which will only be a detriment to their health in the long run.

Care Requirements: A minimum 90 gallon aquarium is needed at the very least for a small Ripsaw catfish. A more subadult specimen will require a 180+ gallon aquarium. The realistic long term accommodations for a juvenile Ripsaw catfish to mature into an adult requires a volume of water of at least 600 gallons – which still barely allows for natural movement as it would freely in the wild. Nor does this accomodate its need to socialize with other Ripsaw catfish, as a group would require a phenomenal volume of water of at least a few thousand gallons. This catfish cannot be put into a biologically immature aquarium. Weekly water changes are necessary to keep water parameters pristine (Nitrates < 15 ppm) as Ripsaw catfish do not like high nitrates and deteriorating water parameters. Equipping the aquarium with several canister filters, or a sump system, is also needed to maintain a healthier environment for this species and combat the amount of waste it produces. A Ripsaw catfish will be relatively indifferent to decor, especially as an adult, but some stacked rocks to create caves to hide, or driftwood, may add some pizzazz to the aquarium. A lot of unobstructed and open swimming space should be of priority, and the aquarium needs to be well oxygenated. Dim lighting will encourage this species to venture more readily out in the open. A sandy or fine substrate is needed, because gravels can be ingested by more mature specimens and get caught in their delicate gill tissue. Ripsaw catfish are compatible with a wide variety of larger, peaceful fish; tank mates should not be aggressive at all, or too small to be potentially consumed. Recommended water conditions, 72-78° F, KH 2-20, pH 6.0-7.0.
