11 Top Catfish Species for Your Aquarium

Pictus Catfish Pictus Catfish is a common species of aquarium catfish. These catfish are very small and can grow to be a few feet in length when wild. Pictus Catfish are nocturnal fish so you shouldn't expect them to be active during the day. 

Upside-Down Catfish These catfish are not supposed to be upside-down, so don't panic! The Upside-Down Catfish was named for its unique swimming and body positioning. It is designed for surface feeding, which is the exact opposite of other catfish species. 

Bandit Cory The Bandit Cory, a peaceful, small catfish species, is named for its distinctive "bandit" facial mask. These fish, like other Corydoras varieties, do well when kept in small groups. Bandit Cory are also nocturnal feeders, so you shouldn't expect to see them often during the day. 

Panda Cory The Panda Cory is a common Corydoras within the aquarium trade. It is named for its distinctive white body and black markings. This Cory closely resembles the Bandit Cory. Good cory health is dependent on water quality and maintenance. Make sure they have plenty of hiding places during the day. 

Bronze Cory The Bronze Cory's overall dusky metallic brown-grey to green coloration is what makes it stand out. These Corydoras excel at hiding, which is a great benefit for nocturnal fish. 

Suckermouth (Plecostomus) Catfish These catfish, also known as the Plecostomus or Plecostomus, are well-known for using their mouths to anchor on plants and the sides of aquarium glass. The special mouths of these catfish can remove algae and other debris from surfaces. Plecos can grow to be quite large so make sure you correctly identify the species before adding them into your tank. 

Three Stripe Cory The Three Stripe Cory's translucent, iridescent body is decorated with a maze made of dark brown to brown lines. This species is also known as the Leopard Cory. It follows many Corydoras care rules, such as nocturnal feeding and strict water quality requirements. They prefer to be kept in small schools of 3-5 Corys. 

Julii Cory The appearance of the Julii Cory is nearly identical to that of the Three Stripe Cory (#7). The main difference is the consistency of lines on the fish's heads. The Three Stripe Cory will have a fully connected design, while the Julii Cory will use an intertwined pattern of dots. It can be difficult to tell the difference between small and large fish. 

Bristlenose Catfish This catfish, also known as the Bristlenose Plco, is small and won't outgrow its aquarium like most plecostomuses. The multiple bristles or whiskers surrounding the head distinguish these catfishes from other species. 

Pepper Cory The Pepper Cory's dark brown or mottled body is what makes it stand out. The underside, pelvic and pectoral fins of the Pepper Cory are translucent to white, but the dorsal side of the fish has a shadowy appearance, which is great for hiding from predators during daylight. This species is often confused with the Three Striped and Julii Cory. 

Skunk Cory Skunk Cory's bold black band runs along the dorsal edge of the fish. It is sometimes confused with the Adolfi Corydoras ( Corydoras Aldolfoi), which also has a black band, but it is interrupted by an orange patch on its head. The Skunk Cory is similar to other Corydoras species and thrives in small groups. They also need lots of hiding places, due to their nocturnal nature.
