Buy Catfish, Corydoras & Plecos Online UK
Browse freshwater catfish for sale online, including Corydoras, plecos, algae eaters and other bottom-dwelling aquarium fish. Catfish are popular for community aquariums because many species are active, interesting and useful for occupying the lower levels of the tank.
Not all catfish are the same. Small Corydoras usually prefer groups and soft substrate, while plecos and larger catfish may need wood, caves, stronger filtration and more space as they grow. Always check adult size before buying.
This category is ideal if you want peaceful bottom dwellers, algae-grazing species or specialist catfish with unusual shapes and behaviour.

Do plecos eat all algae?Plecos can help graze algae but still need a proper diet, including sinking foods, vegetables and wood for some species.
