Catfish are a diverse group of freshwater fish known for their whisker-like barbels, bottom-dwelling behaviour, and wide range of sizes and species. Found in aquariums of all types, they can range from small, peaceful species suited to community tanks to much larger and more specialised fish kept by experienced aquarists. Well-known examples include Synodontis species, pictus catfish (Pimelodus pictus), and glass catfish (Kryptopterus vitreolus), each offering different characteristics in terms of appearance and behaviour. With such variety, catfish can be used to add both function and interest to an aquarium, depending on the species chosen.
Catfish are among the most varied freshwater fish available, with species adapted to a wide range of environments and aquarium setups. They are often recognised by their distinctive barbels, which are used to detect food along the substrate and navigate their surroundings.
This category includes catfish for sale in the UK from trusted sellers, covering a broad selection of species suitable for different tank sizes and experience levels. Some species are small and peaceful, making them suitable for community aquariums, while others grow larger and require more space and careful planning.
Unlike many mid-water fish, catfish are typically bottom dwellers, spending much of their time near the substrate or hiding among décor. Providing suitable hiding places, such as caves, driftwood, or plants, helps reduce stress and allows them to behave naturally.
Water conditions vary depending on the species, but most catfish benefit from stable parameters, good filtration, and regular maintenance. Researching individual requirements is important, as some species prefer softer water while others are more adaptable.
Feeding habits also differ between species. Many catfish are scavengers, feeding on leftover food, while others require a more specialised diet. Providing appropriate food ensures they remain healthy and active.
When selecting catfish, it’s important to consider compatibility and adult size. Some species are peaceful and ideal for mixed tanks, while others may be more territorial or predatory.
You can also explore more specific groups such as Corydoras and Plecos within their own categories, along with aquarium equipment, aquarium plants, and water treatments to support a stable environment.
