Freshwater Catfish

About this collection

Explore our collection of freshwater catfish, featuring peaceful community species, hardworking bottom dwellers, algae grazers, and impressive monster fish. Freshwater catfish are known for their distinctive barbels, unique personalities, and ability to occupy areas of the aquarium that many other fish overlook.

This collection may include Otocinclus, Corydoras, plecos, twig catfish, Shovelnose Catfish, and other freshwater species. Some remain small and thrive in peaceful community aquariums, while others can grow exceptionally large and require specialized housing, powerful filtration, and carefully selected tank mates.

Freshwater catfish have different dietary needs depending on the species. Some primarily graze on algae and biofilm, while others require omnivorous or carnivorous foods. No catfish should be expected to survive solely on leftover food or naturally occurring algae.

Review each individual listing before purchasing to confirm the fish’s adult size, minimum aquarium requirements, diet, temperament, preferred group size, and compatibility with existing tank inhabitants. Always select a species based on its full adult requirements rather than its size at the time of purchase.
