These fish require a water temperature of between 68-79 F (20-26 C) and, as they do well with freshwater fish they are most comfortable in a freshwater aquarium. A proper filtration system should be in place for any freshwater aquarium. The most common aquarium diseases that a spotted catfish can suffer from are bacterial and parasitical infections.

Did you know...

The spotted Raphael catfish (Agamyxis pectinifrons) is the Amazonian counterpart of the spotted sea catfish. Agamyxis pectinifrons, which is indigenous to South America, is a small fish that grows to an average size of 5.9 in  (15 cm) in length. The average spotted Raphael catfish lifespan is typically around 10 years and these catfish are also sometimes known as the talking catfish. More than other catfish, in a spotted catfish aquarium, the spotted Raphael catfish needs a hiding place that they can fit into. Spotted Raphael catfish don't actively seek out other fish for prey, but they are known to eat smaller fish when an opportunity presents itself. The spines on a spotted Raphael catfish are able to tear through nets as they are so strong. One of the main things involved with spotted Raphael catfish care is choosing a tank size of at least 35 gallons and the spotted Raphael catfish proves to be a non-aggressive and active fish species when kept in a group of three to five fish.

Another relative of the spotted catfish species is the Pictus catfish, also known as Pictus cat, polka dot catfish, or Pimelodus pictus. A typical Pictus catfish size is 5 in (12.7 cm) in length, and an ideal Pictus catfish tank is will be at least 55 gallons. A 55-gallon tank is the minimum tank size for this Pictus, bottom dweller. Wild Pictus fish tend to be scavengers, and so in aquariums, they should be fed frozen foods, bloodworms, and blackworms. They make for a good aquarium fish as they have a peaceful nature. Pictus catfish are known to eat small fish and fry as well.

Spotted catfish attain sexual maturity at between four and five months of age.

Spotted catfish in the wild mainly eat insect larvae and small invertebrates. Spotted catfish are only able to eat smaller fish. Their mouths are able to easily capture smaller fish but struggle with large fish.

The sharp spines on a spotted catfish are venomous but are mostly innocuous.

The Synodontis angelicus catfish is another related species, it is found in the Congo Basin.

The natural habitat of the spotted catfish is tropical waters in the Indo-western Pacific region. In a fish tank, it is essential to provide 'hiding places' for your spotted catfish. An aquarium or a tank for catfish also benefits from having live plants. You can attempt to recreate their natural habitat by having good-quality live plants as well as sandy substrate in your aquarium.

All catfish are scaleless fish, and they sometimes have scutes that they breathe through. The pectoral fins on a spotted catfish are used to change direction in the water.

Apart from the Amazon Basin, Pictus catfish are also found in the Orinoco River Basin. This species is in fact, endemic to these two basins. Pictus catfish belong to the family  Pimelodidae, which is a family of catfish with longer whiskers than many others. They sometimes get confused with the African catfish (also known as Angelicus cats or Mochokid cynodontis angelica). Pictus catfish have a combined respiratory system, meaning that they must periodically come up to the surface to trap an air bubble for breathing. Females of the Pictus catfish species are bigger than males, meaning they are only very slightly dimorphic. Pictus catfish are known to feed on fish that are smaller than them, like neon tetra fish. Fish that are too large for Pictus catfish to consume are safe from becoming their prey as these fish are generally non-aggressive otherwise.

What is the rarest catfish?

The Mekong giant catfish and the golden cave catfish are two of the rarest catfish and are the hardest to find. They are both listed as Critically Endangered species by the International Union for Conservation of Nature.

What do you feed the spotted Raphael catfish?

The spotted Raphael catfish is a bottom dweller and a bottom feeder. They are not fussy eaters at all and will feed on whatever makes its way to the bottom of the tank.
